Okay, so freaking out, I was siphoning water out of my male half moon betta tank just now and he kept playing near the tube (I was not use the wide thingy that you use on the gravel) and next thing I now is he is in the tube. I reversed the flow and got him out. I know he lost some scales cause I saw them float out of the tube also. I turned the light out cause he had to have been scared to death (I know I was). Here's my question should I use aquarium salt or melafix bacterial infraction meds on him. Plus should I use something for his slime coat. I am taking the corys and shrimp out after I figure out what I need to do to make sure he will be fine.
