MY crowntail betta Fishsticks (AKA Scaredy) is not acting like himself... I changed his water 50% a few days ago (last time I did a 100% change he seemed really stressed and sat on the bottom), and now he's sitting at the bottom again. At first I just thought he got streese3d again, but I am worried now. He looks fine to me, and when he does get out from under the plant at the bottom he's his perky self, but he seems to be spending a lot of time there, and he gets underneath the plant and stays real still. Sometimes he will sit sorta inside his little cave thing and be pretty still, so maybe he's just comfortable there on the bottom?
HELP!
He seems to look OK to me, so I thought I'd look up stuff on weight or gills, and I thought I'd ask you guys.
He's in a 1 gallon tank (which I was considering getting a bigger one, but if water changes are too stressful to him, then I don't know...) with a temp of about 77-78 degrees, and I keep the light on all the time to help keep the tank warm.
