I have been feeding him the Hikari pellets, and yesterday, I noticed I have not really seen any of his poop (before I added him to the tank, in his bowl, his poop would be pink or orange round clumps). Last night, I noticed he looked bloated, so I put 2 and 2 together. I think he may be constipated. Parameters are pH 7.2, ammo is trace, nitrite is .5 (and dropping) and nitrates are about 5. His tummy looks smaller today than last night, though I still can't be sure I see any of his poop. It is still ever so slightly bloated though. I have not fed him specifically today, but I did feed the 3 livebearers though, a small pinch, and I noticed he did eat a few crushed up pieces, not a big whole one, or even the equivalent. He tried nibbling on the kuhli loach shrimp pellet, but gave up when the loach showed interest in it, despite being much larger, so I don't think he is exceedingly hungry. There are plenty of molly and platy fry around, and I am certain he's eaten some of those, though none are unaccounted for today.
The guy at the chain store said to take him out and give him bettafix. I am hesitant to, since it's going down on its own it seems, and he is otherwise fit and frisky, swimming just fine, playing a lot like he normally does. He isn't clamped, everything else looks fine, just his tum is a little pooched out and slightly blanched compared to the rest of him. I think I'm the only one who'd notice though, it's very slight.
Instead of putting him through the stress of being in a bowl (don't have a good QT tank set up yet) and then having to reintroduce him, would it be better to just not feed him (I have to hand feed him HIS food -the Hikari pellets, which I hate and won't buy again), for a bit, maybe even more than a couple days, being as the others get fed and there are fry around. Or, since the others get fed and there are fry around, it won't improve until I fast him separated from the tank?
It's a 20g, and I do a 25% WC (conditioned with Stress Coat per the bottle instructions) every 4-6 days or so. I check my parameters daily (usually more, I'm kinda OCD, lol), I basically do a small change as needed.
Thanks! I wish I could get a good photo of him. He's a pretty cambodian mutt VT and definitely my favorite of the tank. But I don't have a good enough camera to get a shot, so I can't really show the bloat. But it's just around his pectoral and ventral fin area, I can only see it from the side, and it's just barely noticable. I only notice because I love to watch them.
