I got home from night shift at 6:30 this morning and it's still a bit dark so I decide to shine a torch into my tank and see if I can find anything cool. Well I guess you should be careful what you wish for. I found this sneaky guy crawling across the back piece of glass. (sorry about the terrible photo, he's really fast) While he must have been in there for at least a month now and not caused any harm my tank is no where near occy proof and I am petrified that it is a blue ring, anyone have any clue if there is a way to know? Does anyone have any ideas how I could safely catch him? I am really worried having a possible blue ring in an unsecured tank with my 1 year old running around so I would like to remove it asap. Any help is appreciated.
