I wouldn't think so. They are carnivorous pleco's and I know pleco's like Pseuda's aren't a worry in acrylic tanks since there carni's. I know wood eaters and big herbivores like P. gibbiceps can damage acrylic.
That's one of the things everybody has heard but never seen.. All but "that one guy" who is pretty credible but still can't prove it..
I'm sure enough to call bs but i will still curse my own stupidity (since i knew) if i came home to 500g on the floor because my plecos ate the seal..
Hate those kinds of myths..
Yes! It works! Thank you so much! I added some more malaysian driftwood that I've kept in my smaller planted tanks this morning, not a single plecos on the glass since! Thank you so much everyone!You try feed the Viejas on one side of the tank and when there into the little feeding frenzy put food in the opposite end for the pleco's.
