I have a 10 gallon that I just don't know what to do with. Currently it is well planted, with 2 otos getting to know the place. I wanted a couple of african cichlids, but learned that I need to add salt to the tank, which wouldn't make the otos happy. or would it? I like colorful, fairly peaceful fish. I don't want to overstock, but I also don't want to put just a single fish in there such as 1 Beta. I thought about getting a pair of small Angels, but I read that the otos might be prone to sucking the slime from their flat bodies. Any suggestions for an interesting pair or small group? I already have a ten gallon with tetras..
