inverts

So I have a 10 gal aquarium with a pleco, a betta and two cory cats, recently I have noted ich on my pleco and do not want it to spread but I do not have another tank to quarantine it in. I have seen paraguard but know it is bad for inverts, and there is also a snail, a crayfish, and some ghost...

Hey guys. I recently found these 2 nano tanks on the curb for freeeee! Someone's poor giant pleco and goldfish must have died... RIP in peace :eek:. They seem like they are walmart mini tank kits. I think I found the links to the correct ones here. The big one has pretty cool pimp lights...
