Corydoras

[Dave S]

I'm a bit concerned about the state of my Corydoras (4 x Bronze Catfish and
6 x Virginae) in a 400 litre aquarium.

When first introduced they were all extremely active - dive bombing
together - rocketing to the surface followed by kamikaze strikes to the
bottom of the tank and generally enjoying themselves. Then I introduced 2 x
mature Golden Gouramis and because of their maturity caused serious problems
with other fish. I returned them to my LFS and thought that would change the
situation - no such luck - the Cory's still hide in the undergrowth - and
although they are eating well, there is not the activity seen previously. I
have to be honest and say that over the Christmas/New Year period I have not
been as diligent with my housekeeping as I should have been (20% water
changes every two weeks - fresh food once per week etc). My life style is
such that the aquarium is located in my 'Chill out room' and I use this for
maybe one/two hours per day. Maybe there is a disturbance factor but that
doesn't apply to other fish.

Any comments or suggestions are most welcome.

Thanks - Dave

I think your fish will be fine Dave. Corydoras do not normally "rocket" to
the surface and "kamikaze" back to the bottom. This is a normally a sign of
impending spawning. Corydoras can take air and some ( I have Albino's that
do this) come to the surface occasionally however my others 100+ normally
spend their days on the bottom hiding in their flower pots or some other
form of structure in the tank. The exception is my Albino's which are very
active all day swimming usually from the bottom to the middle of the tank.
