Possibly feces?
A female or male goldfish can be any colour. The colour of the fish does not determine the sex of the fish.
Goldfish should only live with goldfish with the exception of weather (dojo) loaches, bristlenose plecos, or mystery/apple snails.
Yea yea yea whatever!!
The fish is pooping.
Goldfish are best with goldfish with the exception of weather (dojo) loaches, bristlenose plecos, or apple/mystery snails.You should not keep a fire belly newt with goldfish as their needs are very different. In addition, the newt needs a land area, so a smaller tank with partial water and a nice dry land area is best.
Male fish have claspers on their lower belly, so if the fish doesnt have these claspers, then it's a female. I dont know if it's the same with goldfish, but since they're fish, it probably is.
they breath with their gills
That is most likely a string of feces hanging off of your goldfish. It will break off eventually.
On it's Belly, with all four legs under it's belly.
you just put a pices of string under a hole
I doubt that it is because the goldfish is pregnant, but that's a possibility. However, it's usually because of the fish food we feed our goldfish that is sold at petstores. The pellets and flakes are both dry food, yes? And when they go into the goldfish's stomach, they kind of swell up, because when dry foods go into water they usually swell up. So it's probably because the dry food the goldfish ate swelled up in it's stomach.
He played pianos and a 12 string guitar and lots more.
