Ctenopoma should really only be fed bloodworms once a week as too much protein isn't good for them, him preceding pellets over blood worms is good.
Oh sorry, I got confused. Gouramis are the ones that don't need to much protein not ctenopomas. Sorry for the wrong infoWait, I thought they ate fish and insects in the wild? Shouldn't they mostly be eating meaty foods (if you exclude pellets?)
I know bloodwowms aren't that nutritious overall...
I might be misunderstanding you...
