Upload pics of the damage your plecos have done to your acrylic tanks, want to see how severe it is on average before I put any of them near my 240 gallon acrylic.
I've had my panaques in my acrylic 240 and 135 for 3 years. They haven't caused any damage whatsoever. They've also always had lots of wood and veggies dropped in on a regular basis. I think as long as they have enough natural things to chew on they will stay away from the acrylic.
I'm buying an acrylic 8x4x30" in the next 2 years. I currently own:
1xL128 @4"
1xL177 @4"
1x L190 @7"
1x L330 @7"
1x L191 @9"
1x L203 @13"
I am confident that with enough wood they won't destroy the acrylic. But the health of the fish is the most important part to me. Plus I don't want a glass tank that big. I currently have them in a glass 225.
