I have had a betta for 2 weeks now. I was misinformed by the fish store employee (a local store), who told me a half-gallon bowl without a filter or heater was not only ok, but preferable for a betta. Now that I've read more, this advice really pisses me off (specifically since I asked, very pointedly, whether a bigger tank with a filter would be better, and he told me it would be WORSE for the fish).
Bossypants, the fish, has been active and lively and sociable. He clearly recognizes my 4 year old who is the one who feeds him (under my close supervision), for instance. But, probably due to the poor water conditions, he has what looks like a mild case of fin rot, just on the edges. This was what led me to look up more information on bettas and figure out just how wrong the guy at the fish store was.
So, I've bought a 3 gallon tank w/ filter (a Tetra Half Moon Bubbler) and a heater.
I was wondering how I should precede with transferring him. I'm worried since the tank is brand new, and, therefore, uncycled, that transferring him right away would make the fin rot worse. Is that true? Would it be better to keep him in the half gallon bowl, with daily water changes, until the new tank is cycled?
If so, is aquarium salt in the small bowl a good idea until the new tank is ready?
Also, would it be possible/advisable to 'seed' the new tank w/ some gravel from the old tank to speed up the cycling process, or is that a silly idea?
