i have two ocellaris clownfish i think they are a mated pair now they seem pritty chummy with each other all ways with each other etc etc. my question is that the female has developted a verry large underside to her and it is a yellow colour i thought that she might be producing eggs getting ready to lay but a friend at work told me that i could possible be her swimbladder he sed that this is what happens when they have problems with there swim bladder and that the swim a a funny angle instead of normal. my clown is not swiming like that yet and it has just made me wonder weathere it is her swim bladder or weathere she is getting ready to lay eggs ? anyone have any experiance in this ?
