breed

Can anyone tell me what kind of goldfish my fish is? I've had him for about a year and I've tried to figure out what kind of goldfish he/she is! And can anyone tell me how old he might be? Thanks! :) He's the large orange, white and black fish.

So my eels had eggs and I put them in a breeding container so nothing eats them. Some of them floated up is this Normal?

I have 3 blue yellow tailed damsels and I was wondering how do I tell the sexes of them?? Everywhere I'm seeing says characteristics but they give the most generic and difficult reasons so from the experts or people who know their stuff how do I tell??

so i have 3 balloon mollies in my saltwater tank, and they have started breeding. i was mostly just wondering is there any differences between breeding them in saltwater and breeding them in brackish/fresh water? also, how long after breeding will the female usually give birth?

okay so one of my damselfish has been excavating a little cave like area near a rock and a corner of the tank, it's been hanging out by it for about a week and a half now. today i saw that two of my three damsels were swimming around pressing their bottom sides against the rock and like swimming...

Just curious to see how common this practice is. I'm always interested in self-sustainable hobbies, and a starter set from e-Bay is $50. I know I don't have an insane amount of fish, but would love the idea of feeding my fish well....also, I've been toying with the idea of breeding some...

The first pic is of my existing clown, the second is of a clown I got today from Nick. 1) What species are they? 2) Will they become a couple? That is all. Thanks!

Been kinda vacant on the forums for a while, been busy with the move to the new house and all. Everyone did survive the move! The problem is.... My tank has been setup for almost 2 years now, July will be 2 years exactly. The 2 clownfish I first purchased where from the same tank at the LFS...
