About Four days ago, I went to my LFS and fell in love with a little white (soon to be purple) male! I went over to his cup and inspected the conditions. While the water was fine he seemed a little lifeless, but I assumed that was because of the small space he had to live in.
On the way home, I observed him and he also seemed fine, if anything a little bit more happy in his small bag than the cup. I should probably say now that he is only small, so I am assuming that he is younger than my two other males. On adjusting him to the new tank and letting the filter cycle run, he still seemed lifeless. I fed him 3 pellets of Hikariusa Bio Gold Floating Pellets and he ate them fine.
The next day he was sitting midway between the tank and while my other males had a flaring match at there reflection in the betta mirrors, he didn't flare and his fins remained clamped together. I also noticed that he dosn't move his caudal fin, anal fin and dorsal fin. They seem stuck together. I also noticed that at the ends they seem to be more stuck than at the bases.
I am worried that my little Ace has either Clamped fins or fin melt. I've been hesitant to add anything to the the water as is only new to the aquarium and I don't want to stress him out to much. I'm not sure if this is something to do with his young age or if it is very serious. Also he is in a divided tank
Any help would be appreciated, as I am new to betta keeping and I don't want to lose my precious little boy!
