I went to the fish store and got myself a marine betta around 4’. Unfortunately during packaging, it fell down from 5ft and got imediately put back into the bag. I brought it home anyway cause its the last one they have. When i got home, i notice he spit out some remaine pieces of shrimp and all the acclimation time it does not swim but lie down and breath not fast but still heavily. Even when I finish acclimating and put it in the tank, it look so weak and float then got stuck to the outer part of the powerhead. I then took it out and put it in a place with hiding spot and less flow but later i caught him swam out of there and lie down near the front glass. Will it be ok? I turned off the light so it can relax now.
The first image is when i was temp acclimating and the shrimp piece still in the bag wwith it and the second one is when it swam out of the hiding spot
