Ok so I did watch one two of the pairs spawn, it looked like one would lay eggs and the other would follow behind but did not lay eggs. I am fairly certain of at least One male the largest and two females. the smaller pair I'm not positive about. The trio I am 95% I have two females and one male.
I figured it would be nearly impossible to get anywhere in the community set up. The angels seem to protect the eggs from the other angels but don't really pay attention to the Denison barbs which apparently love angel fish eggs. So I will move the next batch out.
I am not dead set on getting large amounts of fry. I think it would be cool to get some hatched, but if it never happened I wouldn't be devastated...hence letting them go naturally for these first 4 or so rounds.
I have a 75 with neons and danios, but I also have a few 10 gallons for the fry to start in. I have sponge filters and other extra canister filters that can be moved around. I have 3 canisters on my 125 right now...I just got a Eheim 2217 and I have two others already on it so bio-filtration shouldn't be a problem.
The first pair (large male and red shoulder female) have had probably 4-5 clutches of eggs, this last week was the first time to get eggs from the other two females.
I do hope to eventually get a few fry to hatch, next time I'll try using a breeder tank instead of leaving them in the community or putting them in a breeder "basket". Maybe I'll get lucky
thanks for the link I'll check it out.
