Retirement and forum shutdown (17 Jan 2022)

Hi,

John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.

I wish to thank John for his hard work in keeping the forum going.

With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.

I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.

If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.

I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.

I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.

Thank you
Darragh Sherwin

Since wacker's stock list seems to have ignited everyones passion . I thought i'd throw this out their for discussion. I was jus wondering what people's views are? Also bearing in mind that to a relative new cichlid fish keeper might have inadvertly put together a pair resultin in a hybrid . What would they do in your opinion? ? ?

Like most people i am against hybrids to a certain degree. There was a time i wouldn't go into a shop if they stocked hybrids or at least what i considered hybrids.

I think the only way to get this tread going is if someone was to take the side in favour of hybrids. I can think of loads of reasons why i dont like hybrids but i can think of some reasons why i like some of them.

All i ask is anyone posting against hybrids post a brief list of the fish they keep.

I love hybrids

P.S. i am only taking the side in favour of hybrids to spark some debate.

i don't mind if a keeper happens to have a mixed species tank and by chance gets hybrids, i have had this happen to me with a male red top hongi and a female red zebra, how ever i would not sell them on nor would i try breed them either. if it happens it happens but as live stock breeders supplying fish to the trade i think that fish species should be kept as pure as possible. the reason for this is that i have been in lfs and ask whats this and whats that and getting a spot on ID on a fish can be hard unless it is really common, could you imagine what it would be like with hybrids???? the offspring of the two above all looked like red zebra's which i could very easily sell on as red zebra's and not hybrids which is terrible if someone was looking to breed them seriously.

kind of contradicting myself a little lol but hybrids in lfs is a no for me

some good points their . But is hybridisation in the wild how we get so many different and new species? I'm not to up on this subject as a few others on the forum but they might imput some of their knowledge.

I personally don't thinks there's any problem with them as long as if someone is selling them or giving them away is up front about it then its your own preference from there.

I'm on the fence

imo hybrids can be beautiful fish but should NOT be deliberately hybred, sold on as true breeds or bred further from, saying that they can be beautiful show fish, as for busters question hybrids can happen in the wild but are very rare due to availability of suitable mates of the same species and generally similar species would not enter each others territory to breed as each fish species would have its own niche in the vastness of these lakes and generally stay in the same location which is why some species are sold with variant names ( where they where caught such as lab. caerulus as in this link malawicichlids.com/mw09001j.htm ) and because of diet look slightly different. hope this might clear that up for you Buster

There is definitely artistic value with hybrid fish. Most of the beautiful strains of Asian arowanas that are sold today in most of Asia esp Japan are crosses between pure strains. Flowerhorns in Asia are widely sought after fish. I would admit to the fact that I've organized a fishclub with this in mind and we are aware of the issues with dyeing fish and all sort of operations and that is not in the hybrid category. So really for me and IMO honest opinion it all depends on the hobbyist. As said before so one should sell hybrids as pure breeds and whoever buys them knows what they are getting. Asian arowanas anyway are hard to breed at home and you need millions to set up a brooding stock with a big lot. So you end up with the breeding of cichlids or flowerhorns among themselves - and i never inter bred cichlids just flowerhorns. I have culled many fries in my early years of breeding Fhs and thats because I wouldn't want to sell them and to put in in hobbyist tanks because of its quality etc etc. So in the end its up to the hobbyist preferences.

(sorry about spelling)

Hybrids and new species plus the loss of current species are a thing of the future. planned hydro dams will bring the demise of some and hybrids of currently seperated species and those to slow to adapt will be lost.

but we should also remember that current species have been developing for thousands of years and will continue to do so.

if one takes for example Astyanax mexicanus born with eyes which then disappear. if they are bread in tanks with lights after a few generations the eyes no longer disappear nature returns to it orignal form.

out side of fish keeping one of the most interesting hybrids i have heard of is the polar bear /grizzly hybrid which was discovered

a few simple rules should be observed
no forms should be kept that cause unnessarry suffering due to psycial defect for example

new strains should be recorded as new strains thus giving the choice which path the indivual wants to follow

the use of chemicals to cross species stopped

other things that should be considered we tend to have a standard that describe, it is what we chose not neccassrly as nature intended

enforcing purity to strickly could equaly lead to the demise of the species as protect as it may curtail natural progression of the species.

cheers She

it is a sad fact, in the past that the cost of importing fish created the need for hybrids so we could have variety! The modern guppy, the London and bristol Shubunkins once most popular being prime examples.

today with global warming loss of habit etc we are seeing an end to the golden age of the hobby! As more and more fish will face export bans or worse extinction.

I am not for or against hybrids but i don't want to be part of the cause of some fish becoming extinct either. thus we must except hybrids not as a villian but as a protector of wild populations by the fact they reduce the pressure on wild stock. there are many fish i would love to own but can't but i can if i so choose go see them in their natural habitat but for how long???????

As long as hybrids stay in our aquariums only, then there is a place for them.

perhaps the real question should be what we can do to ensure there are always pure breed wild caught fish available rather than complaing about fish types being no longer available.

am i against all hybrids and inbreeding. no, there is probably good and bad.
am i against hormone feeding. yes. i can only see this as bad for the fish and the hobby.

hybrids are here to stay. all the colourful swordtails in the hobby were created by an original crossing with platys to get red colouration into an otherwise plain greeny fish. virtually all common ancistris are probably hybrids. most aulonacaras nowadays are crossbred, mostly with other aulonacara but also with certain mbuna and protomelas etc.

fancy goldfish, guppies, discus and angel colour strains etc. are selectively linebred and often inbred over numerous generations, concentrating on minor colour spots or mutations to create the vast range of shapes and colours we see today.

most of these hybrids and linebreds/inbreds are accepted and welcomed in the hobby and create interest and take the pressure off wild stocks. also mongrels as with dogs are usually hardier than pure strains.

the worst fish for unplanned crossbreeding in the aquarium are cichlid species, esp. the rifts
most of the fish we regard as seperate species are probably geographical variants or sub species and therfore will cross readily in the confines of the aquarium. so to avoid unwanted crosses dont keep closely related species together.

Thanks for that insight derek ! Would it be fair to say allot of fish keepers who would be opposed to hybrids ! Would have a good chance of having a hybrid in their tank? As you have also said mongrel's are often stronger ! Would you not believe selective imbreeding would help strengthen the species ! Possibly saving a species by doing so ! I know in cheetah's they could do with some new blood as there lineage is full of incest which could effectively be their undoing!

1 Neolamprologus leleupi
1 Neolamprologus brichardi(daffodil)and a few shell dwellers,the leleupi and brichardi paired off and spawned.This was a first for me to see this,as i have several of both of these species in a tang community together.I will be keeping an eye on both after seen this,these are the guys fish and hybrids

This happened back in the day in the FishFX tang display tank at the back of the shop
Both brichardi and leleupi guarded the fry as best they could. thankfully there was a nice
big black calvus in the tank.

I can see both sides, if it happens in ur own tank well thats nature and once its not for commerical sales throughout shops well im ok with it.

But when its done just to create a new fish well i against that 100%

Sure its natures way of creating different types of fish spieces.....?

Was watching the nature doc on it and isnt that how we have so many different types of fish...?

This is what I thought especially since there is so many similar looking species.

Its not nature though, it happens in the confines of an aquarium where there is a limited choice of partner & no escape for females being harrassed by dominant males... In nature hybrids are extremely rare.

Being so territorial and such great parents it has to be unusual for cichlids to hybridize in the wild.

This would probably not be the case with egg scattering fish who could chose the same patch of weeds as other egg scatterers.

This definitely happens in our lakes, rivers and canals where there is roach/bream, rudd/roach, rudd/bream etc.

African cichlids are all descended from only a few species but their diversity is a result of evolution and survival of the fittest rather than hybridization. It is because of this common ancestory that they can hybridize in the aquarium.

As for the ethics of it. I'm undecided. As long as you know its a hybrid when you buy it then I suppose its ok.

i agree and as far as possible we fishkeepers should try to avoid rearing hybrid fish.
anyway most hybrids are not as attractive as either parent and can be more aggressive.
unlike substrate spawning brichardi/leleupi type situations, in a mixed malawi mouthbrooder tank, it is almost impossible to detect mongrel spawnings till the resulting fry grow a bit. and even then similar species such as the reddish salosi, estherae, johanni, msobo have to be almost adult to id accurately unless you are very experienced.

So would it be more human in the long run to cull known hybrids as young as possible like deformed fry? I don't know if i would personally but i'd imagine i'd leave them in the main tank and if they survive let them be as i wouldn't say you'd shift them on too easy

it is difficult to have a definitive answer to the whole hybrid question but hybrids are the plague of the malawi part of the hobby.
my view would be to try to keep strains as pure as possible but without becoming too obsessive.
without actually witnessing the mating most of us would'nt know the difference anyway as fry can often start out very different looking than the eventual adult form.

to broaden the topic.

in the hobby we also have chronically inbred tanganyikans and south and central americans which are an even bigger problem as this leads to deformed and weak fish.
strangely enough malawis are not as prone as the tangs to bad shape or weakness as a result of inbreeding.
