Angel fish have not spawned in almost a year??

So last June my Angel Fish spawned and I ended up with eggs on the intake valve of my HOB filter. I was both excited and sad...excited because it was their first spawn, sad because of the timing. We were getting ready to leave for vacation within hours of the spawn. Upon return the eggs were gone, no fry to be found.

So now it's 10 months later and they have not spawned again...anyone have a guess as to why??

Thanks

 

My pair of chanchitos took a year for their first spawn Who knows when they will again

Have you been conditioning the fish?

 

What kind of Angel fish are they?

 

Once paired off angels usually breed. Are you sure they haven't been spawning and just never noticed? It is easy to do.

What foods are offered? Any neat products, such as brine shrimp or bloodworms? How about tiny feeders, such as danio fry?

Good luck.

 

Sorry..how do you "condition" them?

Two females will spawn together also. And of course we know the results of that. Mine spawned after a water change usually. Because of a difference in temp up/down usually provoked them.

Not exactly sure, see pic...

I don't want my fish breeding, so it's not something I know much about, but I believe people feed them differently and play with the water temp in order to trigger a spawn.

 

Your profile indicates your tank is only 75F. This is most likely the reason. Angels need warmer temps for breeding.

Thank you, I will try adjusting it up, would 78-80F be more reasonable? Or higher than that?

Someone else mentioned temp changes...I do a vacuum/water change of about 15-20 gal every month. I typically put cooler water back in to give them a little change, and then within a day it's back to normal. This helped last year the one time they spawned, it was right after a cleaning/water change.

Thanks again for your comments.

 

I keep my breeder tanks around 80F. And my angels breed at least monthly if not more often.

As fry need pristine water conditions to survive I also change 50% or more water weekly.

Any time my breeders are unhealthy or when the eater isn't clean they stop spawning.

Good luck.
