Three days ago I bought several adult Mbunas of beautiful color from a friend of mine that has a business selling Bettas and Cichilds. I bought nine of them to spread the aggression around. One of them is stressing out. The rest are doing very good. I have two other tanks for Tanganyikans. Can I put him in with them to see how he does? Or should I put him in my 10 gallon tank? He is starting to breathe fast. My friend is out of town a few days. I have no idea what the poop looks like..have not seen it and he is not eating. Actually my 75 gallon tank now has Gold Ocellata babies so probably not good to put him in that tank. Should I start medicating?
