hi I have set up a Trigon 190 and want to keep coldwater species. I have 3 aquatic frogs 2 weather loach and 2 goldfish that will transfer from another tank and I want to see what is available as tank mates for them.

Any suggestion would be welcomed

Thanks

The Trigon corner tanks look cool. You could put in a nice big shoal of WCMM. I saw some long finned ones in Whackers last week, if you prefer them.

Hi Goldy,
I don't know whether this page is any good ... and you might have seen it before. It suggests some species which could be added in a coldwater setup.

Good luck with your new tank!

Goldfish are very messy and I don't know what filtration you use.I don't like them because you cannot keep plants with them and their colours are two artificial looking for my taste. Only my opinion and if you want to keep them that is fine by me.
Personally I'd get rid of both the goldfish and the loaches and go for a nive community set up with minnows, bitterling, sticklebacks and maybe a gudgeon or two.
At least this would give you a chance to introduce a few plants.
Bitterling have a very interesting breeding behaviour. They lay their eggs inside freshwater mussles. There are some cracking bitterling species from Japan but even the European bitterling is a gorgeous fish.
Male minnows really show beautiful colouration during spawning and stickleback males are stunners as well.
Just my two cents. best of luck with whatever sett-up you chose.

thanks for the replies. I have 2 goldfish to go into the tanks and 2 weather loach and 3 large albino frogs. These are already quite happy but in a smaller tank and need to be moved. I also have a few hill stream loach but I dont know if the tank is too big for them. These are in another coldwater tank with killies and WCMM and wuis. They are lovely but I am afraid taht I will never see them again if I put them into a big tank.

I have been on the look out for coldwater species but they are not easily got and like Holger everyone want to know why I dont put a heater in it. I dont really want it to be a tropical tank but I am willing to put a heater in and heat it to room temperature. This may allow me to introduce some species like danios or maybe gobies.

I will keep looking

thanks

Ranchu are great imo. saw them breeding in wackers ages ago.

Also grow quite big. you wouldn't put too many in a 190l tank. Biological filtration also doesn't work as well and fast in low temperatures as in a tropical tank. The metabolism of nitrobacters doubles about every 8 degrees centigrade, i.e. they are capable to break down nitrites doubly as fast at 24 degrees than at 16. Just one thing to keep in mind before you start introducing big, messy fish.
IMO as colourful as goldfish are as boring they are. Don't do much but eat and you know what....

While we all might have an opinion about a particular species but I do not think that anybody should call any particular species boring just because one thinks so.

and I also stated that if you want to keep them that is fine by me. Personal observation, no judgement on others and their preferences. Please don't start again. I got ripped to shreds when I suggested that Derek Doyle shouldn't have written the same thing about Discus and Frontosas. I'm not suggesting that there is one law for some people and another for the rest but it sure smells like that

just taking the **** holger
