Picked these up today as part of my "diversification" to be able to produce a wider range for local lfs's.

I heard you have to get wild caught in order to breed. For some reason the captive bred don't. Is that true?

Not heard that myself. I think it's probably another old wive's tale to be honest. There is absolutely no reason for the fecundity of a captive bred fish to be any different from a wild one unless it is a hybrid. IMO.

that's what I would think too, but I heard that and wanted to ask. I'll try to find some resources on it.

Ok had these guys 4 weeks and it looks like the action is starting. They paired up after about ten days and the third fish was removed as he was being bullied. The male seems to have chosen a pipe and is actively swimming in and out of it. The female also occasionally swims in. The feed very well and like Chopped mysis the best, which I feed as much as they will eat. I did have a setback in the past week when the male caught whitespot which waged war on my fish, but is under control now and no fish were lost. ( Lesson learnt with central sump and no UV. Commercial steriliser now on order.) You can see on the male the marks left by the white spot. The female was unaffected, which is strange as the clown females were mostly affected rather than the males....... Anyway I can distinguish the male as he has blue under the central black stripe. The female has much less. Also the male has more pronounced red around the gills, similar to my redheads in breeding colours. The female is getting fatter by the day and I would take bets she spawns in the next couple of weeks. Water temp has dropped a little in the last couple of days so I have cranked up the heat pump to maintain temp. Ok here's some pics.

Tank bred elacatinus oceanops breed in aquarium. All my F1 pairs are breeding with temperatures around 30ºC. I know its too hot for them but here in Portugal temperatures are very high this summer.

Jeez, is everyone having a heat wave this week? The whole world? Haha! We are having an unusually hot week too for this time of year anyway... Congrats on the spawn! I will be a regular visitor to your journal as I am considering this specie as well. Do you mind posting pics of your broodstock tank please?

Pulled the eggs yesterday afternoon because I was working late last night. Nothing hatched this morning so put the eggs under bright light, gave them a shake and managed to get a few to hatch. Hoping the rest hatch tonight and don't get killed by fungus. Here's a pic of a couple that did hatch.

Really difficult to get a shot of these are their right in the middle of the pipe.

No success with these, I think I may have disturbed them removing the pipe to take the shot. The male ate most of them and the few that were left didn't hatch

Spawned again Sunday morning sometime. Male is tending the eggs and reluctant to come out and feed, so I don't think they have been there that long.

Moved the eggs to a BRT Friday night 28th, but nothing had hatched in the morning. I tried the shaking routine and managed to get a few to hatch. Still no more hatched last night although the eggs dont look dead from what I can see. Will leave them tonight and remove any left in the morning. I can see 5 or 6 only swiiming in the tub at present.

Not having much luck with these. Hatches are very poor and the male seems to be eating or loosing alot of them prior to hatch. They spawned again yesterday but they eggs don't look that adhesive and dont seem to be sticking too well to the top of the tube. I will maybe change the tube after these and rough up the interior to see if that helps. I still have a couple of swimmers from the last hatch and as with the Redheads the larvae appear to be actively hunting on the sides of the BRT. The reason I say this is their heads are nearly always facing the sidewall. I have added some plastic plants ready for the next batch which I think will get populated fairly quickly with pods. From my observations of elacatinus thus far I am sure the larvae hunt on sides and substrate (or at least very close to). I remember the Redhaeds kept the top 2" of the BRT completely clean where they constantly grazed the side.

Had a small amount of eggs hatch last. I found them in the bottom of the BRT when syphoning it. Lets see if I can get any of these through Meta.

Hopefully you have some luck with this batch! I haven't been able find E oceanops so I'm not progressing with you.

That's a shame. I'm not too sure I will get very far with these as I found them whilst syphoning the bottom. Doesn't bode well!
