Tank Switch, Game On!

HI angelfish folks:

I decided to switch my koi angelfish pair into a 33 gallon high tank after struggling with water parameters in their 29 gallon. My pair seemed unhappy and not getting along in the 29. Their previous spawn was 3.5 weeks ago.

I moved them today and they immediately seemed happier in the new tank, much more active and no more aggression. Water tests perfect, unlike previous tank where I was dealing with ammonia. Breeding tubes are visible and they are busy cleaning their slate! Spawning seems imminent:


If they do spawn, I am now debating whether to pull the slate and hatch out the eggs separately or give them another shot at raising the fry themselves. I had no survivors from their previous spawn, but I never saw them eating fry or eggs. I think the wigglers just didn't make it in the 29 gallon with the poor water quality. This time they are in a much better environment. I had a big plan to pull the slate, hatch wigglers in one gallon jar, raise fry in a fry rearing jar etc. But now I'm thinking they deserve a chance to raise the babies themselves. I would really like to see how they do, even though I think pulling the slate will give a better chance of fry survival and I really want some baby angelfish!

 

Beautiful fish! And I would like to say good job for removing them out of their old tank, I agree Fry would not survive in those water conditions. Anyway, Good Luck with your project!

 

Beautiful pair I look forward to following along

 

Beautiful pair I look forward to following along

Agreed. You heard it from the angelfish master haha

 

UPDATE: My koi pair spawned tonight. Man, the female was racing back and forth in their 33 gallon tank, furiously cleaning their spawning slate and an internal filter, the male dutifully following her lead. They ended up spawning on the slate, maybe 400 eggs or so?




I decided to pull the slate and hope to hatch out the eggs in a one-gallon jar. Wish me luck!

 

How are the eggs??

 

Approaching 48 hours post-spawn, I'd say about one-third of the eggs have turned white:

Seems to have stopped though, so I am hopeful there are still a good number of fertilized eggs. I have them in a one gallon jar, 82 degrees, air stone and a few drops of hydrogen peroxide. Hoping for some wigglers tomorrow!

 

Awesome! I'm looking forward to an update tomorrow!! Congrats!

 

They look great, congrats!

 

Sorry to report that I got zero wigglers, no eggs hatched, all turned white. Back to the drawing board...

 

HI angelfish folks

My angelfish pair continue to baffle and befuddle me. After they spawned two weeks ago, I pulled the spawning slate and planned to hatch out the eggs in a one galling jar. None of the eggs hatched. I had them in plain tap water and some drops of hydrogen peroxide. I don't think these water parameters worked.

Since then, the male has been acting very defensive in the tank, attacking anything that come in or near the tank. Acting like there are eggs or fry in the tank even though there are none!

My female laid eggs again last night, but I never saw the male fertilize the eggs. He has paid no interest to her, didn't help clean the slate with her as usual etc. Unless her fertilized the eggs when I wasn't watching (possible I guess) I do not expect these eggs to hatch.
