Last night I came home and found my small Banggai Cardinalfish stuck to the back of my wavemaker. No fins or anything got sucked in but the fish is weirdly shaped like the letter ‘s’ now. It is still alive but cannot swim properly. Now it is just laying on the sand. I feel awful and don’t know what to do since I’ve never had an incident like this happen. Can it heal from an injury like this? or should I euthanize it? In the photo you can see how the fish is kind of stuck in this curved position. :(
The tank is a 40 gallon breeder, the pair of cardinals usually stayed on the opposite end of the tank away from any flow.
