i 've got a 29g tank with 4 small plants and 8 ghost shrimp. I plan on getting a striped rafael and about 4 otos tommorrow. I was think ing about getting some tiger barbs later next week but i keep reading all these bad things about them. Will they be a problem for the otos or any other fish i might decide to get? Or can someone suggest a viable alternative. I just want some sort of colorful schooling fish. Thanks.
