I have two bettas in a divided 34 litre tank. Tankmates are two otos and two amano shrimp.
Both the bettas are suffering from finrot. One had it when I bought him and I thought he was beginning to improve, but now the other fish has it quite badly
His fins look like they have been shredded
I will go to lfs tomorrow morning - please could you advise what I should get, and whether it is safe for the other tank occupants? I do have another tank which I could shift the otos and shrimp into, but I'm not sure if it will be a great move for the otos as it is a new tank with very little algae as yet.
