LF small tank - Edmonton

[kimax]

It's coralline algae so it's on there good. I end up scratching the plastic really badly when I try to get it off. Acrylic would work as well, I just want to get rid of the plastic. (I know many people like the look of coralline algae, and I do, just not on the front or sides of my tanks)

I have read about mantis species breaking glass but have also read that many people believe this to only happen rarely in larger species. Anyone care to comment on this? Experience?

No idea what species he is. Have had him about 6 months and has not really grown at all. Will upgrade as he grows, if he does.

Thanks in advance.
