3 months ago I moved my community from a 55g to a 180g, I also moved (40 miles). The 180g was in place, set up, and biospira added. Fish were moved separately in large 15g tupperware storage bins, sorted by fish size. Move went well, everyone adjusted, etc...

Water conditions ok, ph 7, am 0, no2 0,no3 <30, twice a week 30-40% water change.

The problem is my pangasius catfish. See seems depressed. In the 55g there was a bubble wall that was hers. No other fish allowed in the bubble wall. This 180g I decided not to use an bubbles and all she does is swim in a 3 inch space at one end of tank all day long, except for the occasional panic attack and "breach".

Should I put the bubbles back in?

Will she eventually hurt her self running into the glass or has she already?
 
I took the bubbles away because she was becoming obsessive about the bubbles. All bubbles all the time.
 
If a fish came swam near the bubble was, pseu would chase it away. This was a 55g, so now in the 180 it wouldn't be as much of a problem.
 
Another thing that might make an irridescent shark depressed is that they really like to have a buddy. They say you should keep them in at least a pair but 3 is better. This might make her perk up a bit. I have 2 of them and they always swim together. Always.
 
I'm scared to get anymore due to size issues. They can get rather large.
 
From what I have read, they can get to 3 feet which means the one you already have will probably outgrow your tank anyway. My 2 were given to me along with the tank, and I will keep them as long as I can, but then they get too big back to LFS they go. I have also read that if the tank is too small for them to grow to max size, their body will stop growing and their organs will still grow causing their organs to get smashed and they eventually die from this. I am not 100% on this fact though. I would say that you should either get another, or give this one away to someone with another one b/c it would be a lonely life for this little lady being alone like she is. I am guilty of keeping a blackskirt tetra without any companions also, so dont feel bad. I have not had mine for very long, so by all means I am no expert, but I have been really trying to study all the fish in my tank and this is what I have learned about this species so far.
