I have 2 tiger barbs left in my tank when i stupidly decided that only having 4 in a 12 gallon would be fine. It was good for a couple months, but I woke up and one was missing a stomach, and then another one went through the same thing. My biggest guy is getting hit by karma and is getting destroyed by the smaller one. I don't want the tiger barbs anymore because I want to add either apisto's or bolivian rams to my 29, but the Petsmart and Petco and Aquarium Adventure will not take them because they could be diseased. I also don't have the knowledge or supplies to ship them to a user on the SnS. What would you guys do in this situation? I'm capable of euthanizing the one getting beat up constantly because he is slowly dying, but the new bully will be by himself destroying the other fish in my tank. I feel bad killing him, but I really don't know what to do with him. Someone helpp! Thanks in advance.
