How to shoot through curved glass

[Ginu]

Yep I am aware 34g is small for a tang, however it wasn't planned(fish was given to me as it was going to die in tank with two 10" + tangs) besides the fish was only 1.5-2" at max, so for the time being I think it was ok.

And I had no choice in regards to putting him into a 2g... It was the only thing I could set up as a qt in a very short time.

By the time I moved him there, the fish was on its side, so the last thing he was going to do was swim around. I just need to know what disease that was in order to make sure it doesn't spread to the dt.
