What bottom feeder can I safely put in my tank which has 1/4 inch Dempsey fry in it?They are in a tank which I do 50% water changes every other day and tank has gravel also.Was thinking about some very small corydora's.It's a 20 gallon tank.

mr limpet;4751426; said:I would take the gravel out but I'm afraid I will lose the biological filter if I do that.It has happened to me before.If I keep an eye on my nitrates do you think I will be ok?
mr limpet;4751973; said:I took out the gravel.Water parameters improved already.I have a AC70 and a old Penguin 200 filtering the tank.Both intake tubes have sponges on them too.Thanks for the advice.
