So Zebo, my blue veil tail. I bought a 5 gal for him. An all he did was hide out in the bottom corner by the heater :( He came up for air and that was it. I did water changes every other day. I checked the readings and all was good. Now he's in a kritter keeper that's almost a gallon but not quite. An he's the most active I've seen him since I bought him and his color is really shining and just popping out! In his kritter keeper he's getting water changes every other day and I check the ammonia every day. Checked it today and it was 0.
So my question is... do some Betta's just prefer smaller? I know Eco loves his 1.5 and I'll probably move him to my 5 gal (:3 Actually the LFS is having a sale on 10 gal tanks for 13.99... hmmm)
