Mine too. That's why when we order pizza I eat just one solitary pepperoni sliceA tropical fishes stomach is as big as their eye. Professional say feed this much once a day since they will attempt and will try to eat more.
5 is prob normal. I think I have 10 different kinds or styles right now. Maybe 11
I have floating (2 kinds) and sinking cichlid pellets, cichlid crisps, tropical crisps, discus flakes, tropical flakes, bug bites, shrimp wafers, algae wafers, tropical granules. Some I bought because they were on sale. Others they love. I use up a lot every month. Occasionally I get something to try no one really likes. Like beef heart pellets once. No fish would eat them. My dogs loved them tho, lol
I have 19 tanks, I don't know how many fish. Over a hundred. 3 tanks are just a single fish. Mostly cichlids. Some are too aggressive for tank mates. Another has only 3, one has 6, one has 8. Most of those are big fish. Wife has angel fish tank with only 9 in it. And another with 4 cichlids. So, other than size, they're not heavily stocked. Unfortunately, some of those bruisers need their own big tank, so it can get expensive and crowded, lol
Haha! One splashed water out on the floor today between the back of the lid and tank edge in that couple of inches. I heard the water hit the floor and went to check, and this big 7" blood parrot was swimming away when I rounded the corner. He was like, " wasn't me!"
