Otos died with big round belly

[IllusionX]

Today, 2 otos died out of 15ish. Both had a huge round belly. The rest, at least those who are we're not hiding looked fine.

I wonder what could have caused this. Ate too much? Sick fish ?

Many otos are wild caught ,so I would be very suspicious of internal parasites.
I would watch rest of tank carefully.
Hope this helps.

These are captive bred.

I've got another dead, and one more that is bulging too, but not dead yet.

....Dropsy?

I'll do a water change. Got .25 ppm nitrite..

....Dropsy?

I tried looking this up and couldn't find much. If my otos have dropsy, is it contagious, 3 have died already which a big belly like this and I found a 4th one laying on the substrate still breathing, but not doing much, with a huge belly.

Another thing, snails' shell are turning white?

Dropsy is generally not contagious but it's hard to say because it's less a disease and more a symptom. It can be caused by a whole host of different pathogens.

I'm so sorry Poor fish! We lost our beloved male betta, our first fish, to dropsy last October :'(

I hope no one else passes on, and I'm sorry for your loss
