a S. Petricola, S. Polli, S. Multipunctatus, S. Lucipinnis,...now maybe another type of Synos that I haven't kept like the previous 4...would be nice. I am even open to Botas or other Catfish...to Pleco or not to Pleco...that is the question. I often find that Plecos grow more algae from nutrients than they consume lol...
