Couldn’t resist a beta splendens in a fish bowl yesterday (March 6, 2017). Watching this fish is so relaxing. He simply moves around so slowly and has such a beautiful blue iridescent color. I’ve kept them alive like this for years. Soon as I introduced them to community aquatics (30 gallon) they got bullied to death by other small species. Funny thing about it, folks think they need heaters for the small tanks. Sure, go ahead and cook ’em alive or don’t. If the water is that cold, a small lamp will heat it up. I have a lava lamp near by mainly for the aesthetics. A glass of water comes near to room temperature fairly quickly. The best thing, I’ve learned, is cooler water holds oxygenation better. Not cold! Cool.
The water looks cloudy in the photos. It gets siphoned off twice a week and settles back down. The fish get fed twice a day, three to five nibbles each. It’s therapeutic to watch ’em eat those tiny morsels. They follow my fingers and eat from the surface. The male has a fine bubble nest but I can’t imagine how difficult it’d be to raise betta babies. Males are awfully aggressive. The lava lamp works as a heat source.
