Guys is it adviceable to put a 2-4" pleco in a tank occupied by a 11-12" ornate and 7 " albino sen and 11-12" silver arowana.I hear plecos can kill polys D: any advice ?
the only advice is remove the plecos, they dont kill you bichirs instantly, but they will suck the slimecoats of your bichirs, and your arowana may also be a target. I had this experience before, others may not, but still I wouldnt risk it. Bad tankmate..
if im not mistaken mine was labelled 'marbel' pleco.it looks like a common but it has a darker body and white sorta spots.i will try taking a picture soon.
While its true some plecos have been known to develoup a taste for slimecoat, at that size I would be more concerned with your ornatipinnis trying to make a meal of the pleco and choking on it. Then you're left with two dead fish and a real disaster.
What they said^ most of the time it doesnt work so generally a bad idea.
king what kind can 100% safely be kept with bichirs,because i like my plecos too so im interested.
