(URGENT)

I’ve had a 12” mokelembembe for about a year and it’s been doing pretty well. This morning (around 9am) it was hanging out with my weeksii bichir and everything seemed normal, though it didn’t eat right away. I just passed by the aquarium (12pm) and he started spiraling rapidly and swimming all over the place rapidly. I caught it in a net and and checked it out. The only things I could find is some red on a couple of the fins and 2 diagonal scratches near those injured fins. My guess is either the green sunfish (I’m planning to move it out since he built a nest and started being aggressive when others get close to his nest) possibly attacked it or it got scratched on one of the rougher rocks in the tank. I pit the bichir in a 5 gallon black bucket for now with a low water (for easy access to air) and put some aquarium salt in for now. Any tips for how to treat what is happening? I will say the water quality is probably not 100% since I had to replace my fx6 with a new one recently and could only transfer so much media over, plus been busy this week and haven’t been able to do a water change this week until today (it’s a little overdue, though not by much)9135FDEA-1471-4A3C-A6D3-BA19E8F2F108.jpegA7887126-68E1-432B-AA4E-94745A4538A7.jpeg

Anytime I have an issue with fish. I revert to basics. Check temp, Nitrates, PH, Ammoinia. Even if everything looks good. I do a 50% to 75% water change.

Sometimes we never know. What the cause was. Could be something completely out of your control. A birth defect, a heart attack. Etc
Try not to let it bother you.

True. I’ll try not to let it bother me.

It’s been hard since I’ve been losing a lot of fish in different systems to stuff like this (not the same, but like they are doing well for a while and then suddenly die in less than an hour). I can’t figure out anything that could cause it and none of the systems are similar in any way.
 
Sorry to hear what happened.

I enountered the spiraling and swimming erratically on my senegals. I have a few died and when i checked the mouth, it had trumpet snails on it, likely it greedilly eat the pellets and swallowed some MTS as they do it. They likely choke and trying to take it off by swimming erratically. I was able to save one by placing it on a swallow container and it spatout the snail. It is rare accident, but i cant get rid of my snails.

Sorry for the loss. The fish also appears to be a Polypterus polli, not mokelembembe. Redness is usually a sign of bacterial infection. My assumption would be something internal went wrong causing it to spiral and swim erratically. Unfortunately, once they do start spiraling and swim erratically, they tend to not make it.
 
unfortunately the tank crashed last night due to a mishap with the circulation. Lost everything except my weeksii, a barb, a snakehead gudgeon and a bullhead.

what is the main difference between polli and mokelembembe for Idebtification

Markings are very different. Headshape is different too but that might be harder if you are fairly new to bichirs. Maybe The Masked Shadow The Masked Shadow can share a photo of his mokelembembe.
