View Full Version : Exploding Zebra Danio fish, or is it pregnant?
01-22-2010, 05:49 PM
Well, I've noticed this fish in my tank, is getting bigger, and bigger. I have 4 other of the same fish in there as well. I believe this one is female, but I am not 100% sure. But I also read that there is a disease where a fish explodes. So I really don't know. I can see lumps on the bottom of its stomach, it look similar to eggs, but like I said, it could just be ready to explode or something.. I need to know ASAP because I need to know so I can put it in a baby net so it won't eat its own eggs. I shall post a picture, but I am sorry for the quality, because it was difficult for me to take a picture of a fast moving fish.
Thanks in advance.

Welcome to the Fabulous AC!:22:
Is the tank cycled?
She may be pregnant or bloated.Try feeding her/them some blanched peas.
Make sure they are soft,peel them and sqish them as you drop them in the water.
Danios are egg layers and like a coarse gravel substrate to hide the eggs in as they are laid.If they are not hidden the others will definately eat them.
Marbles work well too.
Spawning requires temperatures of up to 78 degrees, and can be triggered by raising the water a couple of degrees near dawn, when spawning normally occurs. 300 to 500 eggs will be scattered across the bottom and on the plants. I would remove the adults if possible,they will eat the young.
It takes two days for the eggs to hatch.The fry are tiny!Be careful doing water changes.I would use a bucket when cleaning so you can search for fry after vacuuming.

How long do they usually take to lay the eggs?

That depends on the fish.If it is stressed in any way then it may hold back on dropping them.Your tank is bare and if she does decide to drop the eggs they will get eaten.
Have you tested your perameters lately?
Is the tank is cycled properly?

Uhm.. my mother usually does that, So I dunno. It kinda looks like its scales are poping off, but I'm not 100% sure. It's kinda red towards the tailfin.

Both my danios are doing the same thing. We are experiencing something of a heatwave and the guy in the petshop thinks it could be that but I'm not convinced. Any help please?!

It looks like when my Danios over-eat.
Cut back on the feedings, or even starve the tank for a few days.
This will help everyone clear out their system.
Faster fish like minnows/danios shouldn't be given more food than they can consume in just a few seconds per day.
Just noticed the date on this, but oh well. Might help Jamie, regardless.

Its possible its become eggbound. Some users have had success getting eggbound danios to release manually.

One danio looks better, the other worse :S maybe espom salts?
Thanks for the help, will starve them for a bit
