Doing one in a community tank with stupid fish is the worst! I have a few different livebearers, Normans Lampeye Killifish, a school of Neons, Corys, shrimp, and some snails. It’s an absolute nightmare! The platys are always trying to stick their noses into the sucker. Not to mention how dirty they make the tank. I normally don’t have trouble with my tanks (besides that one), as one is a solo guy who doesn’t care, 2 is an outside patio pond wheee the fish just sit in the non-existent corner (it’s a barrel with pond liner in it), and 3 is just me in the forbidden corner (no fish ever goes there).
