A Big Mbu Puffer

  • We are currently upgrading MFK. thanks! -neo
is he still swimming around or always on the bottom? is he running into the tank walls and items in the tank?

He's still swimming around in the aquarium. However he is not nearly swimming as actively as he has in the past. He is definitely sick.
 
I can ask the owner about the diet. He had this condition happen with his last Mbu Puffer and this condition eventually resulted in death. If any of you on the forums are experts with puffers and have seen this condition what should be done about this condition? Even though it is not my Mbu I would hate to watch such a great aquarium fish die.

Agreed: I think we would all hate to see it die as well. However, we still have no idea what this "condition" actually might be, since we still know nothing about the back story on this fish, its diet, what may/may not be happening with the water chemistry, etc.

Maybe you should have the owner come on here and help us try to help himself?

Cujo passed away today. The owner had been feeding him crawfish and prawns. However thinks what killed Cujo is when he changed the diet to include clams as well. Sorry for the terrible news. It did sound to be something intestinal though as because Cujo was bleeding from his anus (never had before) along with the already inflamed stomach and throat areas. Possibly a clam shell lodged in his digestive system that lead to death.
 
Sorry to hear that. FYI that I feed my Mbu whole mussels on a routine basis. He poops out very sharp shards of shell without any apparent issues. They are a crustacean eater and I believe their gut is designed to handle food items like that.

edit: You might find the topic of thiamine deficiency interesting, especially in regards to prawns and clams as a regular food item...

Thanks for the article it was an interesting read. Thiamine according to your article I think was probably not the case as Cujo was being fed live crayfish regularly.

Damn, very sorry to hear of this news. Maybe an embedded shell fragment?

Possibly right now that is our best guess.

Not sure if puffers can get it but it sounds like symptoms of dropsy, especially the bleeding anus, that is the only thing that I know of that causes that

We are no sure what cause his death however something is happening and the owner is going to have to change his aquariums conditions if he wants to keep another Mbu Puffer. He had a previous Mbu (Pojo) that was the same size and age and died the same way a Cujo and everyone thinks it is not a coincidence. For now RIP Cujo.

Thiaminase deficiency may have been an issue he was regularly being fed live crayfish and that is a possibly source for Thiaminase.
 
Doubtful that crayfish were the issue. My Mbu is probably one of the biggest in captivity and I've raised him on 95% whole crayfish for his entire life. That's actually an ideal diet since it is a freshwater organism and the since the puffer is consuming the entire animal, rather than just a part of the animal.

I hope your friend has better luck with his next one. They are really a special pet.
