Constipated betta?

[trennamw]

Well, semi constipated. My Betta doesn't seem super sick, or bloated at all, just maybe 20% off the most active I've ever seen him. But I've seen this twice now ...



And that just doesn't quite look right.

It happened once after giving him Cobalt color flakes and this time after giving him New Life spectrum Thera a. His usual food is top fin betta bits.

I'd like to feed him a "better" food, preferably the NLS, but maybe I have to get him his own instead of the community fishes blend? I think NLS makes a betta one ...

Water parameters are 0,0,0-5 ammo, nitrite, nitrate. 7.5 pH. Temp 78. Large water changes at least weekly. Water supplemented with coral and Equilibrium to get KH and GH up (my tap water is practically distilled).



And that's Bob. Tank is fully cycled, he's alone in there with some live plants, whisper filter ... Had a few tiny spots of cyano but they went away.
