I recently upgraded my 2 lotls from a 10 gallon to a 46 gallon bowfront. It has sand an a cave, filter, bubbler and i am gradually adding more hiding. I am wondering if it would be okay to have 5 lotls in this tank. Also, I am having a very difficult time finding lotls about the same size (5 inches??). I hard its best for them to be near the same size but if I need to go bigger or smaller which would be best?
