Newly Paired Clowns Spawning

Back in the late fall of 2010 and winter-spring 2011 my clown pair started spawning and I was planning to try to raise some fry, but I had a partial tank crash late spring that year. Over the last year the pair was moved a few times as went through different plans for what to do with them and with how I was going to reset up my tank.

Late winter this year I decided to set my tank back up as a fowlr, and put the pair back in the tank. Just about the time all the fish seemed to be settling in together and everything was running well, my male clown went carpet surfing. In mid May my lfs got in some ORA tr percs, including one that looks to me to be a decent picasso pattern. The picasso was not much more than an inch at the time, and my female is close to if not more than 3 inches.
They paired up almost immediately when introduced to each other, but I did not expect him to be sexually mature for a while, he was smaller than my previous male when it was purchased and it took the previous pairing a year to start spawning.

A month ago I noticed the pair scrubbing my overflow pipe on day and I thought it looked like prespawning behavior, but since they had only been together a month and he is still very small I didn't expect them to spawn. The next day they had a small spawn on the pipe, maybe 200 eggs, probably less than that.

In the last 4 weeks they have spawned 4 times, the tank is warm with the summer heat and the eggs are hatching at 7 days, and she is relaying on the 8th or 9th day. Todays spawn is double the size of any previous hatch I have seen from her, even from before when I had counts in 400 range. The angle of the spot they have chosen makes photos nearly impossible.

I was wondering if anyone else has had a mature female take an immature male as a mate instantly, and then had him sexually mature within a month?
The male is still less than an inch and a half nose to tip of tail. I have also seen recommendations not to add fish if you want a pair to spawn, and I added a Singapore Angel (Chaetodontoplus mesoleucus) to the tank less than a week before they started spawning.
 
If the fish you bought was in a tank with a few other fish it could have turned male already before you bought it, and yours was solo so it turned female, not real common to happen, but it is possible. you got lucky, people spend alot of time and money trying to get a breeding pair and not have that kind of success, congrats
 
Big momma and her first mate, he was wild caught from PNG.

The current pair. I will try to get better pictures later. I just scraped the glass and it has a lot of morning light reflections.

it can be 8 months or so for a male to be sexually mature. so mostly the breeder had the clowns for atleast 6 -8 months getting it to that size and another days o4 weeks in the lfs before you got him and another month in the tank with you could put that male at 9 to 12 months old.

the female might be happy and laying again with the new male, but is the male fertilizing the eggs and are they hatching? during the 8 days of the egg cycle are they turning silver for you? have you stayed up to see them hatch or are you gonna try to raise any fry?

your clowns are very nice btw. momma has nice markings.


i would think that adding the new fish would upset the tank and they would stop spawning for a while until they feel safe enough with the new member around. this could stop them for a week to months. who knows.
 
They spawned for the first time a week after the newest fish was added. The eggs have been developing normally, orange first/second day, dark brown with eyespots by third/4th, full eggmass developing, getting silvery 6/7day, hatching 7th/8th. I havent stayed up to watch a hatch, but the mass has been gone on night I have expected the last 2 hatches.

I expect to be moving the tank within 3 months, so Im not going to put any effort into raising fry till I get them resettled and spawning again. The female is a very easy going fish, I dont expect her to have any reservations about starting up again after the move.
