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

Aeration & Pleco Lethargy

Hi,


A lot of us keep plecos and I ma wondering what you think about how they behave depending on the oxygen level in the water, obviously there should always be sufficient aeration, I am talking about the difference between sufficient and over the top aeration:)

I have noticed in the last 8 months the difference between normal and very high aeration. My Panaque is far more active as well as my Rusty and Adult Ancistrus. The Rusty pleco is active anyway, but I have found in the high oxygen levels they are hyperactive, as is the Panaque, much more active and brave. I have switched between levels of aeration a few times and it is always the same, they rest a lot more with just sifficient aeration, I can tell it is sufficient as they don't fan their fins for air or hang about the near the defusers.

Just wondering as we know plecos can be quite a boring fish at times, not that that would ever stop me keeping them:)

Hi Mark,
I think you're on to something here alright.

My Flash Plecs are way more noticeable since I added aeration, more active and more competitive. But its not like they're on a high - they still hide and cram themselves into bits of bogwood for hours on end if they feel like it.

I don't know much about all the different plecs and panaques, but I know the L204s come from areas of strong current and high levels of oxygenation,

Jim.

might it be to do with carbon dioxide levels as well?
lack of oxygen may be noticable by fish gasping at the surface, whereas high carbon dioxide would tend to produce more lethargic behaviour (and the CO2 effects would also be pH and carnonate buffer dependant as well). Aeration would help reduce carbon dioxide.

On the whole, I'd class these fish as 'high oxygen/low carbon dioxide' species.

its funny i was just watching my plecos the other day and noticed how active they were,
i had recently moved them to a bigger tank with alot of aeration, my sailfin who used to be very quiet
is always on the go now,

@Ian
CO2, hmmm may have been a factor alwight, especially since I was changing 80%+ a week in the tank so I'd say there was plenty of it present maybe.


There is obviously a severe abundance of oxygen in a river compaired to still water so maybe the river types prefer the massive aeration
