I was just given a male Crowntail Betta two days ago from my step-father. He was in a bowl a bit larger than a baseball and yesterday I moved him to a half gallon vase. I happen to have a ten gallon tank and a spare heater on hand, and am interested in moving him there. I'm probably going to rinse some nylon stocking and tie it over the filter intake, or maybe just purchase an undergravel filter. I will have roughly $35-$25 left after purchasing various other things at the petshop, including some Angels for my 32.(: Now, Amaro has an affinity for gravel (loves staring it down and doing his half-flair at it. Silly boy.) and I don't want to deprive him of his fun. I don't think I have enough to cover the aquarium bottom adequately, though. I feel I have roughly less than three pounds on hand. I also have a five pound bag of blue gravel. If I put down the blue gravel and cover it with my beautiful pea gravel, do you think this will be enough? He will be the only fish in the tank, and there won't be many decorations for a bit until I get some more money. I also have to take into consideration purchasing some medication for finrot and some frozen/freeze-dried foods. If I purchase the undergravel filter, I'll have about $15 to spare for the medication and foods. I have a bubble-releasing clam thing and a bubble wand as well as a ceramic castle ornament I can put in his tank. The clam has spikes on it, but I don't think I should be too worried about him tearing fins on them. I'll post a photo of that tomorrow for your opinions. I also have three floating glass fake fish I may put in with him. I'm worried about stressing this fish out too much from all the moves. He's my little boy and I'm petrified of losing him. He flared up completely for the first time not long ago. He's really my pride and joy. He's got so much personality and has amazing blue eyes. I can't turn the light off over his bowl, as it gets too cold if I do. Will the constant light hurt my shy little one?
