Trouble with Angelfish Breeding..

I have a pair in a breeding tank and the female tube has dropped then the males about 2 days later about 2 days after that the male started getting aggressive with her and not letting her on his side of the tank, then both of there breeding tubes retracted and no eggs [she is still fat with eggs]. They have laid 3 times in the main tank eggs were eaten up pretty quick mostly by the BN, there breeding tank is a 30 tall with only 2 corys, I know corys need to be in a group it's only temp., params. are good, any ideas? Tomorrow I will rearrange what little is in the tank.

 

What fish is this?
Edit: just noticed it’s in the angelfish section...

Angelfish, it's posted in the angelfish section

Just noticed.

 

It's OK I've done it also.

 

Anybody?

 

How big was their previous tank? it could be due to smaller quarters. You said they spawned successfully in their other tank? What are the dimensions of their breeding tank?

New scenery can have this kind of affect on fish. Its new territory now...you know? I had this same thing happen when I moved a pair from a community tank into a smaller tank for spawning.

 

They went from a 40L to a 30 tall with only a upright for eggs and
a few plants temp is close to 78 dig.

 

I'm assuming you mean gallons not litres as a 30 litre tank is only around 10 gall8 s.

My experience is at 78 they won't spawn as frequently. I typically keep my breeding tanks at 80.5 degrees and they will spawn every 7 to 14 days in there.

I also like to keep plants either fake or real to give them a sense of safety I find it does help although I have seen breeding tanks were it was just a breeding cone and nothing else.

Is she still big with eggs? If so you could try raising the temp slightly and doing a large water change. It might help induce a spawn

 

Yes gal., I have plants in front of and behind the up right I had hoped they would lay on about 3" away all around it, it looks like she may have laid and eaten the eggs today as she is no longer plump in the belly and the male is no longer running her away from his side of the tank. Maybe have better luck in a couple of weeks.

 

Hopefully next times a charm. Keep us posted.

 

Fallowing. Can you post the GH,KH, and ph? My pair were successfully spawning in my high tech set up with a ph of 7.6. Now that I'm no longer high tech my ph is back up to 8.2, and they haven't had a successful spawn since.

It may take a few weeks for them to get comfortable enough in there new tank to spawn for you.

 

I have pretty soft water down here, if I remember right the GH took 5 drops and the KH never did change color even after almost 90 drops, my ph in that tank is 6.8 as of this morning.

That's perfect ph for spawning angels. They should do well. Good luck.
