I've got two 20 gallon fish tanks. One has a bristlenose pleco and 5 tetras, one has 4 corycats and 4 nannostomus and a ton of plants. I am thinking of merging the two tanks as keeping both clean is a lot of work, but I am afraid the pleco will eat all of my really nice plants! The tank he is in now has some big anubias that aren't doing great, and no algae, I think because he is taking care of all of that. My other tank has Java moss, small anubias, java ferns, an amazon sward, and a val. It has some algae here and there but I have 3 nerite snails that keep it pretty much in check.

Thanks!

No, they wont eat plants. And generally nothing will eat anubias, the leaves are too thick, there are some exceptions through. Bristlenose plecos will eat some film algae but not actual plants. Because of their size they're one of the safer plecos for plants as some of the larger plecos can damage plants that get algae on them even if they aren't deliberately eating them.
