AHHH! I think my little guy has escaped and is probably dried up somewhere in my apartment! He was still in the 150 yesterday, but now it's nowhere to be found. I had done a 50% water change yesterday and rearranged some rocks and driftwood so I would be able to see him more often. I think I may have upset him and caused him to jump out. The tank is not completely covered due to the two HOB filters I'm using and yesterday might have been the first time since he's been in there that I had filled the tank all the way up to the top. I've looked everywhere in the tank and there doesn't seem to be any hiding spots that I have not looked at already so I truly believe he's gone. Dang it!!!
Woo Hoo! The little guy just appeared behind a rock last night when I was feeding the fish. I couldn't believe my eyes since I really thought he jumped out the tank. I'm so happy he's back/still in the tank and alive and well. Here's a couple more pictures of him. Eating very well and I hope to see a slight growth spurt in the coming months.
