Autopsy of a Red Melon.
I want to find out what causes the death of this fish. She stop eating 5 days ago and became bloated. Number of treatments starting 1 tespoon per 10 gal of Epsom Salt didn't work. Last one was yesterday at 2 teaspoon per gal. That's the swim or sink treatment. Unfortunately, She sank this AM. at 8:25 am. Autopsy was performed. I'll let you make your own diagnosis. She's the only one affacted from the juvenile tank of 25. The rest of them never have enough to eat. Constantly bagging for food.
Subject: Red Melon juvenile first looking bloated.
Equipment.
Red Melon 3 months old. 3inches. Aggressive eater. Helathy until 5 days ago with bloated GI tract. Food were BH mix. - BH, Shrimp with shell, garlic, vitamin B complex; Red Wrigglers. Tetrabits.
Cut open reviewed bloated stomach, Bladder- small and normal, anus passage -clear, Liver-normal and red. Gill - Clean, no worm found.
Close Examination reviewed the right decending gastric passage appeared blocked. Others Left and Middle decending are inflated with fluid. Inflated stomach appeared mostly fluid.
Cut open the Oral passage leading to the stomach is clear and patent. Fluid escaped out, no food content found when cut open, no worms found, clean and empty. Linings in good shape.
No bloackage from the anus to deodenum. No worm found.Gall bladder is nomal, no ovaries found.
Duodenum cut open reviewed black healthy feces.
Cut open the r decending Gastric passage reviewed shell of shrimp which may have caused the death of this fellow. May this hungry soul Rest in Peace. Amen.

Re:Autopsy of a Red Melon.
Jimmy,
Thanks for the info, sorry about the fish though. This is really interesting as never seen a set of pic's showing an Autopsy. Learn something everday! Also now know not to feed the shells of shrimp to the discus, though would this also happen in a larger fish? I ask as I just bought some Mysis shrimp.

Re:Autopsy of a Red Melon.
WoW! Jimmy......
I know that had to be a little heart breaking ???
How often do you do autopsies? I think I'd really have a hard time doing that to one of my Discus..... it would be another story if it were red fish, flounder or trout ;D
Anyway.... glad you found the cause
I was seriously thinking about using live grass shrimp in my Discus's diet...(they're plentiful here and free of charge) .... on second thought....."NOT"

Jimmy....
Just a thought here..... do you know what I'm referring to when I say grass shrimp ??? They live in brackish water in my area and are very small. They also sell them in the lfs"s around here for most cichlids :-\
any thoughts on this.... would this be a good thing for them ???
I tell ya... it sure would be hard to peal those little guys :-\ if they're are any possitive benefits to feeding them I may give it a try :

Hi Jimmy!
Sorry you lost that fish! But that was a really good educational use you put its death too. Nice work on the autopsy and shell fragment. I often wondered about whether it was better to leave the shell on or off when making beefheart. IT look likes there is at least a potential for the shell causing blockage in younger fish.
Thanks for sharing!

Re:Autopsy of a Red Melon.
I'm not familiar with the anatomy of the fish. There're 3 tubes distal to the stomach. The blockage is not the tube connected to the Deodenum, that explain why Espsom Salt did work. What's that tube for.? It could be the tube for the water to come out from the stomach. It's the narrowest of the three. It looks like it never went through the digestive process and went out from the wrong tube that caused the blockage. Anyone had a diagram of fish organs.? Please don't feel sorry for me. I'm glad I have one less to feed. I still have 24 of them don't know where to put them. Another 150 BD coming up. Discus is fun and challenging.

Sorry about your loss. I am very impressed by your post mortem work. Very informative. I am glad I do not put shell in with my mix.

Re:Autopsy of a Red Melon.
Very informative Jimmy.
I saved this picture of an autopsy by Phog. It doesn't answer your question, but as long as we're on the topic it clearly shows the location of other internal organs.

Re:Autopsy of a Red Melon.
Excellent Carol. thanks. that' s the antomyof the left side of the fish. Mine is the right side. That's complete the full view of the antomay of the discus. I'm glad I went to the right side. Otherwide I wouldn't have seen the blockage. i didn't see the ovaries. My fish must be a male or not yet developed any sexual charateristic due to young age.

Exceptional post, very well done. There a lot of pics like that in Dieter Untergasser's book. It give us all a good look at what's going on inside our Discus. Sorry about the loss.
