i just talked about this in my last thread, i thought it was awesome. lol
there was a 5 gal (idk it just looked twice size of mine) and i asked the lady about it since my local petsmart didnt have that. She seemed like a betta expert.
she told me it was her own tank that she contributed to show a happy betta and how they should live. I was so happy someone finally understood.
she said she picks out the best looking healthy fish to put in there and once someone buys it she replaces it with another in the big tank.
also, in this petsmart every male had a bubble nest and was active :)
Miami Ice- a unsocial butterfly who swims away from me everytime i pass his tank.
