Thank you for your advice. I have a total of 10 fish in a 20g tank. I
don't think overcrowding is a problem. One thing I neglected to mention
is that I have eco-complete as the substrate which can have rather
sharp edges. I also have a very small pleco that is doing very well, I
don't know if that says anything about the water quality at the bottom.
Also, what does adult mean for anglefish. Mine are already breading and
haven't been too much trouble, is it going to get worse?
