any locals?

Nice tank I would use a razer blabe if they are on the glass get the blade under the zoes and scrape away. They do come off easaly. Then peal what you can off what ever else you don't want them on use gloves. Then if you want to frag them further use a rasor blade and cut them up. put them in a pail of salt water to rinseand then into recovery tank. 5 bucks a frag and away you go, now you are a farmer.
