Betta Anatomy

[pens]

Betta anatomy should be analogous to almost any teleost fish, but bettas are so small it would be difficult to differentiate between organs (or any piece of tissue resembling one for that matter) unless you have a microscope at hand. I don't think it's possible for fish to expel an organ (prolapse maybe), but... ouch. Sorry about your betta!

Oftentimes poorly digested food can seem strange as it is expelled especially if your fish eats large pellets and doesn't chew his food properly

My bf did an autopsy of my fish and found large white masses. Due to our inexperience with this so far, we've concluded that it was either a bacterial infection within the swim bladder, or tumors that grew to the point that his organs shut down.
I personally side with the tumor idea because a) I don't believe he could have lived that long with a bacterial infection of this size and b) he had had the lumps (at a manageable size) for months without any swimming issues.

Doing your own necropsy on your fish? Wow!

I'd be too sad to do that :(

I've wanted to do one for a while. I just don't want to do it until I have a good microscope... Preferably one that you can hook up to a computer and save the images

Yeah... I don't have the funds for that :/

Any progress? I'd be interested in seeing too. I was actually looking for a labeled diagram of the outside of a betta, like what each fin is called. But this would be interesting in a 'different' way :D

Interested as well... Always wondered about the organs and what they actually look like... should I ever have the guts (pardon the pun) to perform an autopsy on one of my fish, I'd like a guide to know what I'm looking at.

Though I'm not so sure how I'd go about dissecting him/her... as I already can barely stand to see their dead eyes staring at me...

Refer back to post 13. The OP's boyfriend did the necropsy and found tumors. There were no pictures.

Without a photographic microscope wouldn't go very well. A betta's organs are so small that even with a zoom on a camera it would be hard to see in any usable detail.
