So I have found two obstacles for keeping Synodontis Petricola fed in my mostly Malawi tank. For the first obstacle of competitive eaters I feed the catfish during the night when the lights have been out for several hours. The more serious obstacle MAY BE that at least on of my Malawi species (Pseudo Elongatus Chewere) is sensitive to anything besides Spirulina and anything else runs the risk of bloat. This means the catfish are eating only spriulina in this tank. I was told this was not enough for their dietary needs. So I am looking for some tips on keeping the Petricola.
