Clownfish swim trouble?

[762pmcs]

I have a clownfish pair, and the male may have an issue swimming to the bottom of the tank. Looks like he is struggling when swimming down, and only gets about 2/3s the way down. They've been in DT for 3 weeks now after 6 week QT, they had Brook. They are the only fish in DT, along with a crimson shrimp and some snails and hermits.

Curious if this is an issue or normal(ish) behavior. Working on attaching a video, at end of video female nips at him, is this the reason he doesn't go low, or is something wrong?

Param range past few weeks:

Salinity 1.024-1.026
pH - 7.8-8.1
dKH - 8.2-10.1
NH3 - 0
NO2 - 0
NO3 - .03-.05
PO4 - 0
Ca - 441-566
Mg - 1300-1500

Looks like your clown may have a spinal injury. Notice how it appears to be slightly curved to the right hand side and the tail's motion is restricted.

He def does not move in the same motion as the other. Guessing there is no treatment for that if that's the issue?

Sometimes it heals by itself.
