My puffer tank grows algea very quickly and would love to put a pleco in there to help control it. I know that puffers are semi-aggressive fin nippers but what if the pleco is bigger than them? Or any other advice. Thanks!
You might be better off posting this in the Plecos forum. To the best of my knowledge Plecos will not like a lot of salt. This depends on the salinity of your brackish water. a tsp or two per 5 gall will not hurt but any more than this may not be too favourable.
Oh just remembered - what about a small school of black mollies for sorting that algae out they like it brackish. To be honest plecos create more mess than they clear up and when they get a bit older algae is neither here nor there because the majority require a bit more than just algae. Mines currently on honeydew melon, celery and lettuce.
Them puffers might be hard on the eyes on the bottom dwellers -even if they are alot larger then themselves.
Ive got 4 puffers in diffrent tanks and the algea problem is a constant problem. Clean the tank sides and let the algea roam free over the rest. Might even look good.
Tried diffrent flatbellyfishes -didnt work. Tried big appelsnails -didnt work. Tried shrimps -didnt work. They just dont like other fishes -except for food...
