hi, I am thinking of MAYBE getting some bottom-dwellers for my tank (specs below), but haven't decided what yet. if I do get anything, it wont be for quite a while, until the tank is full of live plants. I was thinking ottos, but I've heard they are delicate, and my tetras are very agressive towards each other, always ripping each others fins, I don't know what they'd do to other fish. I like corys but they dont' eat algea (but I am still considering them anyway, but I like lots of options). whiptails are just ugly IMO. what other bottom fish would fit in my tank and stand up to my tetras?
