I moved my bp to a new tank last week and it had been going well until this morning when my wife screamed and I looked to find my bp heading under the refridgerator. I was able to grab her tail and stop her. it took so doing but i was able to get her out unharmed I believe. could see no signs of damage. but my question is how can I prevent this from happening again? it's a 50 gal kritter keeper with the slideing screen on top. she had pushed it open enough to get out. right now i have the sides duct taped. I dont think she can get out now but I need a better fix. any sugestions?
