My Betta boy (cup said halfmoon ... looks like he could be delta though) I rescued from Petco a bit back is driving me nuts. He simply does not like to be in a glass tank ... and it only worsens with the light on. He get's too stressed in a glass tank, seeing his reflection is certainly part of it. Giving him time to adjust didn't work ... nor did using backgrounds, etc. I bought him his own 5.5g complete with Stealth heater, filter, etc. I've also had him in a 10g. He didn't like either! Matter of fact, I recently tried him in the 5.5g again ... and he became so stressed, his tail split in several areas. He's a vivd blue/purple ... and HAD nice tail finnage. The ONLY thing he's liked and appears comfortable in ... is a 4 gallon white bucket. The bucket has decent dimensions (16" L X 10 1/2" W X 10" H). He can't see his reflection ... and there's obviously no lighting. What I have in there are a Hydor 15w mini heater ... a smaller sponge filter ... hamster tubing floating on the surface and placed on side/bottom ... and a floating silk plant. Problem is, while he's happy in the bucket (and that's what's most important for his well being) ... I didn't exactly envision displaying him in a bucket in my room, lol. Any ideas for something that's less reflective? I've considered a Lg. or XL Kritter Keeper ... as it may prove a bit less reflective than glass and there's no light.
