Hi all, New to the forum, but not new to fish keeping. I have two bettas, the one that is acting strange I've had for about a little over a year. He resides in a 2.5 gal tank, water is declorinated and changed every 7-10 days. Latest change is three days ago with about a 1/8 tsp of aquarium salt.
Healthy up to now. A fin nipper though not severe so his fins always seem to look ragged. During his last water change, I lifted him out of the tank using his hiding glass. I've found this to be a very gentle way as not to scare him or stress him during his changes as he can scare fairly easily.
For some reason he freaked this time. Since the water change he is very reluctant to come to come up for food which he would eagerly do before. Yesterday and today I did get him to come up once or twice for a pellet but he dashed back to the bottom almost as if he were out of breath.
He also seems more lathargic. Though not as active as my other betta, he is less so now. Spending more time sleeping than before sometimes seeming to pant.
Thanks in advance for any thoughts.
