After going from cycling the tank with one lone bluegill, to around 20 tropical fish ( platys, neon tetras and corys) I'm wanting to make sure I do not:
1. overfeed them.
2. underfeed the corys
I see some of the flakes make it to the bottom, but I'm not sure it's enough for 4 corys. today I added some flakes straight to the water-flow and got them to the bottom. Is there a rule on how much to feed based on something other than the "what they can eat in 2 minutes?" I'm a little concerned that the corys aren't getting enough to eat.
Also, the corys will sometimes rush up to the top of the tank and hit the surface. I've got plenty of air in the water (oversized waterfall filter), but are they gulping air or trying to jump?
LOL They don't look like "jumpers" to me, but what do I know? ha!
