Tail down, using pectorals, but no or not much tail is spinal. Tail up and using the whole body and noticeably using the tail is swim bladder.I'm bumping this because my lineatus in QT is exhibiting behavior that could be swim bladder or spinal injury. I don't have a video but can get one tomorrow.
I've had the fish since Black Friday. It's been in QT since. I QT for about 2-4 weeks. Eating pellets, mysis, brine, basically anything i put in the tank from day 1.
About two days ago I noticed the fish starting to swim funny. Tail down, head up. Pectoral fins doing most of the work. Swim bladder immediately popped into my head so I put it on erithromycin. Monday will be day 3 on it. Today very little swimming, mostly just getting blown around by the powerhead in the QT. Tried eating and would try to swim on its own but just always seemed to just miss the food. Later in the day I found it resting upside down on the bottom. I moved one of the pieces of PVC in the QT and it awkwardly swam away upside down.
I do not see any bulges in the abdomen. Just the odd swimming behavior.
Swim bladder? Spinal cord injury? Something else?
Should I continue with the erithromycin? Try something else?
Thanks.
For a spinal injury there is not much that can be done. Some fish recover, some don't.
