7. Were the fish placed under quarantine period (minus the first batch from the point wherein the tank is ready to accommodate the inhabitants)?

b. Heater? A heater (just the kind that's a tube you stick in) rated for 20 gallons

b. Appearance of poop? normal
c. Appearance of gills? normal, rapid breathing
14. a. Have you treated your fish ahead of diagnosis? no
b. What meds were used?
I'll be honest. I bought the oto cat because I had seen him in the fish store looking like he was going to die for several days in a row. He was laying upside down and was extremely thin. So, being the dumb person I am, I bought a guppy breeder/isolation thing, stuck it in my tank, and put the oto in the breeder (after slowly acclimating him to my water, of course).
He has been slowly improving (I think) but is still very sick. He basically acts paralyzed most of the time, laying sideways or on his back and twitching slightly. If you use your hand to create a current, he'll kind of just drift around, not making any effort to save himself. He breathes pretty heavily, almost gasping. I have been providing algae wafers as well as some weighted down algea-covered leaves from my aquarium plants. I assume he has been eating as he looks much less thin and has been pooping but I have not seen him eat nor have I seen him attach to the sides or to anything like they usually do.
Sometimes he CAN swim, and he'll swim aroud extremely quickly and panickedly, but when he's acting paralyzed, you can take him out of the water and he won't do anything to save himself.
I'd like to let him loose into my tank to give him a chance, but I tried and he just sank to the bottom on his back, and I know that that would be too tempting for my ghost knife to harass him.
What could this possibly be? I know I shouldn't have bought a sick fish, I just felt bad for him. Any suggestions? I really want the little guy to live.
Just providing the limited info I have on the subject. Apparently, Otos have a less than average survival rate unless tank conditions are pretty much ideal. As I understand, they are all wild caught. That being said, and I appreciate your good intentions, you have a real uphill battle ahead of you. If he's eating, that's a good sign. Make sure he's getting mostly vegetable / algae based food. Almost sounds like swim bladder disease, but I don't think that would apply to an Oto. Hopefully, our experts will contribute here.
Thanks for your reply!
I have read in my research that they are sensitive. He looked pretty much starved when he was at the pet store. I, too, hope for some expert knowledge in this troubling time (for my little oto)
I can say that Otos like a strong current in the tank. It may be that it helps them breath. I'd remove him from the guppy breeding pen (or whatever it is).

Well I suddenly really, really feel your pain. Just discovered the healthy — albeit too thin — Oto I brought home yesterday to school with my other two died. No idea why. It was swimming, munching on an algae wafer, and generally just being an Oto a few hours ago. :/
That's stinky. I'm sorry. Mine is so abnormal... He's still alive now... Dumped him out of the vase and he's just laying on his back. He's less thin but the movement thing is so strange
