Injured kuhli loach
My kuhli loach is injured or something. He is swimming sporadically and in circles. Sometimes he appears dead, then will become spastic. His neck appears slightly kinked and sometimes he pants.
-It's a 20G, cycled, with tankmates listed in my siggy. They all leave him alone, never even notice him really. It's filtered and heated, at 78-79*. There is also a bubble wand. Several live plants.
-pH is running high- 7.2, so I know for a fact that's not good for the loaches, but ammo, nitrite both at 0, and nitrates are 5. I had added Aq salt at the beginning, when we first started the tank (late December), but I've done several 25-30% WC since then. I have no test for the salinity to confirm, but I doubt there is much left, especially since I dosed it conservatively to begin with.
-My water change schedule is every Saturday, a 25-30% change, and I do a stir method with a turkey baster on the gravel as well.
-He has lots of hidey places, my substrate isn't sand, but it's small pea gravel and he can dig through it.
-He and his pal are fed 2 API shrimp pellets each night, and they also obviously get any leftovers from the other tankmates, which are Aqueon tropical flakes (pinch a day) and possibly the betta's NLS pellets but he usually eats those up. I put half a cube of frozen bloodworms every Friday as well. But, I don't think he can eat. He can't seem to swim well and only swims in circles, and totally spastically.
Because of his crazy symtpoms, I want to get him in a separate tank so I can possibly medicate him, reduce his stress from tank mates, be better able to control the pH, which is a problem for me at the moment, I believe it's our tapwater. Also, I am worried he isn't able to eat much, if at all. What should I do? I bought him a 1.5G with a Tetra Whisper filter. I don't have a heater yet, but will be able to get one. I also have Melafix, epsom salts, Aq Salt, Stress Coat, but I am not sure how much is safe of these things, if at all. Kuhli's don't have scales, so they can't take as much as other fish.
I really want to give him a chance. I bought the loaches without noticing the salinity issue and the site I used for info gave the wrong info on the pH. If I can just keep him well enough til I can rehome him I would be happy. If not, I do have clove oil, if it would be more humane to euthanize him.
Thanks for any help!
