Konvictkeeper, I've got 3 fresh waters 2, 30 gallons and a 10. The 10 is set up with feeders leftover from my octopus as well as a couple platys and a small catfish ended up in there after we emptied another tank. One 30 is a Amazon setup with angels, tetras and a pleco with blackwater and low ph the other 30 is just a fun mix of freshwaters my wife decides she likes, I think a betta female and a ton of mollies right now. My big salt water (30gallon)has a juvenile humu humu trigger, 2 clowns (1 black , 1 reg.) with their anemone and 2 yellow tail damsels,and whatever is left of my turbosnails and emerald crabs after the humu humu had his way.
