I want to have a Pleco or other catfish in with my Discus to help keep the tank clean. What kind of catfish can I keep with Discus?
A. If you keep suckermouth catfish such as Plecos with Discus, it is advisable to keep small ones such as Clown Plecos, Zebra Plecos, or Otocinclus. Larger suckermouth catfish such as some plecos can cause serious damage to the skin of the discus if they decide to latch on. Even Otocinclus, which remain small, have been known to attach to the sides of the Discus, so use caution with them. Some people have problems, some don’t. See above for info on Corydoras catfish and Discus.
