Today was a feeding day so I used tetra crisps. The pkg says about 1 crisp per inch of fish. I have 13 fish, 3 of which are about 2" and a couple of them are about 1.5" so I put in around 17-18 crisps. I think the big fish (mollies, cherry barbs) got it all while the tiny glo lite tetras just kept trying and not succeeding. Should I be worried at this point? I am thinking of putting the pig mollies in the new 10 when I get it but until then they will have to share quarters.
