Hi, everyone. I have never owned a betta fish. I bought one last week from PetCo (all of their fish looked really good). I was very impressed with his beauty and health and he is doing very well! He has so much vitality and charm! He makes me happy and I love him. His name is Horatio and he's either blue, green, or both, depending on the angle. He has a small tank (1 gallon, I think) with a heater, thermometer, filter, gravel, structure, and lighting. I have seen him blow bubbles and noticed this morning there were a few small patches of bubbles at the top of his tank.
Well, I went to Wal-mart yesterday and saw a little guy in cloudy water, his back was bent at what can be exagerated to be a 90 degree angle. His fins were close together (not fanned out at all) and he exhibited no activity. The exact opposite of the fish at petco. I took him home and named him Quasimodo. He looks like he has both scoliosis and sclerosis. I put him in a vase (I know! It's all I have! I promise I'll get him something better within my budget!) with spring water, some gravel, a heater, and a thermometer. His fins are now a bit more fanned out and his back less hunched. I have seen him blow bubbles. (To what extent is this a good sign? I doubt he's making a bubble nest in his condition). He has definitely perked up, but still look sickly and swims slowly, though I am glad to see him swimming at all. He is also finger shy. I have fed him and he ate, though it took it a while for him to do so and he didn't eat much. He has a black body, crimson fins, and blue scales on his anterior and some some blue on his dorsal fin. Help me help him.
Both heaters are self regulated, so they're not on all the time.
