I've been keeping fish for a year now and have three tanks
One 20 gallon for mollies to breed ( some are food for piranha) have 7 in there, yes it's crowded but most fry end up as food or occasional adult.. Sorry but it works well for us.
40 gallon for my cichlids have 6 and a pleco in it ( have some cloudy water issues in this tank and unsure how to clear the water...
And also a 45 or 50 gallon for my piranha that tanks doing well clean and he's quite a hungry little guy !
Any tips on clear water and tank setups are appreciated. All water from all tanks are tested and are at rigt levels. Any other tips on feeding and proper care are appreciated! Thanks for your time ! Hope to hear from you all
