Dallas hadn't been feeling so great maybe 5-7 days ago, but recently he's been on the right track... he would flare once, and then the next time I tried to flare him the same day he wouldn't. I've tried on the weekend too, and he flared once- but he hasn't really since.
He's raised his gills very briefly to a mirror, but that's it... he spreads his fins a bit too and has kind of a mean staring-competition with his reflection.
Tank is .75- hospital- he's always been in there since I got him (maybe 2 weeks ago or so, I believe). Temperature is at 78, and I do water changes either daily or every other day. Depends on how busy my schedule is.
Otherwise he's very healthy, he's active, he loves his food, he'll jump for it- he just won't flare!
