Urgent! Dying Clown Knife!

[Nevergone815]

I just purchased my first ever clown knife on Saturday. He's in a 20 gallon by himself until the 75 finishes cycles (yes he'll go into a bigger tank then the 75 when the time comes) he's about 5" right now. The last 2 days he's seemed perfectly healthy, but today I found him lying curled up on his side, he's still alive and will periodically swim in a circle then go back on to his side not moving, I did a 50% water change, but not sure what else to do! Please Help!!!

Sadly it sounds like the cycle took its toll on him, don't think he will make it to be honest.
Research fish before you add them to a cycling tank, there isn't many that are hard enough to go through a cycle.

The 20 gallon is cycled

Sorry read it wrong.
Sounds bacterial to me and he in bad shape to be honest, Try a bacterial med.
Good luck.
