so I'm not sure if I can keep one of the earth eaters in that tank, or if it will turn it's aggression towards the other residents... it's really strange, that there is not a tattered fin on any of them, yet they battle almost constantly, and at this point, don't fight with anyone else, but they do bounce off of everyone & everything, when they are battling each other... I've not had any luck, even gifting them to the local pet store... thinking if I can leave one in the tank they are in currently, move one to the Bichir / Silver Dollar tank... and 2 of them are going to have to go into holding tanks... I really only have one 10 gallon empty right now ( actually I have a spotted Silver Dollar, I've been growing out, in that tank now, but it's big enough, & used to the food, so it's ready to move in with the other silver dollars )... I'm sure adding 2 into a 10 gallon is a recipe for disaster so I'll have to figure out the 4th one, maybe for real temporary, into the failed scud tank, ( also a 10 gallon )... I actually have 2 cupids coming, that were still in my basket, & didn't notice them, on another order ( they better actually be cupids this time... different supplier, so fingers crossed )
