Do catfish tolerate sera mycopur?
A question about sera mycopur: The treatment contains copper compounds. Is it dangerous for catfish (L 18, Corydoras)? Do you have according experience?
the copper level is very low and will not cause any problems for most catfish species, nevertheless catfish should generally be transferred into another aquarium unless they are affected themselves. This especially applies to animals that live in acidic water with very low carbonate hardness (copper is more effective, but also more toxic under these conditions than in alkaline water and/or water with higher carbonate hardness).
