Black Shark

[Vip]

I was moving my 75g out of my old house and i put my black shark in a container with a lid on it, well he kocked it off pretty fast and hit the ground hard i put him back in and this time i gaffa taped (very stong tape) the lid down he then tryed to get out another 3 times hitting the lid very hard! then he stopped, not a sound out of him then when i put him in his tank 1 hour later he just sat there leaning towards his right side and not wanting to swim, a couple of hours later u put some food in and he did swim over to it but it seems as though he was struggling or was in pain to do this, is it possible that he may have cracked his ribs? its now day 3 and he is swimming a little bit better but prefers just to sit there like he is resting and there are no signs of injury on the outside of his body as well..

Any ideas?

It is quite possible he has hurt himself trying to escape. There is, however, not much you can do about it other then give him a quiet stress free environment.
