You will need to remove either the perpetrator or the victims to a separate tank until they're more evenly matched.

Females of the dwarf Julies (ornatus, transcriptus, Kombe/Gombe) are typically 1/2 the size of the males or less (size, not length)

They pair up (male/female) in a basically monogamous relationship ... although occasionally they will practice polyandry (single female, multiple males) ... so you might see a triple (1f, 2m)

Once they pair up, any which are rejected may be killed off. The tip off to an individual being rejected is going up to, and hanging in, the top corners of the tank, hiding behind a heater, etc.

As far as them not eating, don't bet on it.

They may not come out and eat when you throw food in the tank, but you aren't seeing what's happening when the lights are out ... or when you aren't looking.

They will eat lots of the aufwuchs, growing in the tank - see:

https://en.wikipedia.org/wiki/Periphyton

The photo below, which I just took, contains a pair of Julies ... and about 50 of their fry:

I usually toss just a pinch of flake food into their tank daily ... but could probably get by with just letting them feed on the brown diatoms growing in the tank ... and what lives in/on it.

They are incredibly fast little buggers ... :lol:

There's a reason for that torpedo-shaped body.

It's also a good reason to have an overly large net.

Your experience is unusual. Maybe choose another vendor and get juveniles so you have several months when they don't care who is a boy and who is a girl and just play. I start with six.

IME the fish rejected happen one at a time and I have a couple of days of seeing them lurking at the top...plenty of time to get them out. Whatever is left once peace returns is your pair.

Sorry not bern online, so put 3 back in main tank, cant believe the one i left on its own is still alive as bit beat up bless him,
So one is having a go at another any time it sees it, and dominates the tank taking the big cave, now the other i have seen with it in big cave occasionally for a short time but then its chased out so maybe theses 2 may pair up eventually, i dunno its been really trying sorting these bleeders out, watch this space

Cheers

When I first got into Julies, I found the breeding notes here https://www.cichlid-forum.com/phpBB/vie ... p?t=347649 and here https://www.cichlidae.com/article.php?id=422 helpful.

One thing that stands out in both is the idea that pair formation is encouraged or enhanced by a joint defense of breeding territory. Whether the two are working to kick out conspecifics or others in a community tank/introduced targets it seems to me the process is the same.

Second, pairing isn't necessarily immediate and pretty. This isn't a Disney romance. Instead you'll often get bickering, nasty attitude, and general conflict until a pair has bonded. And for sure, letting them choose who to bond with is less demanding than trying to work out an arranged marriage. Conflict between two Julies doesn't mean they won't eventually bond and spawn. And there is some suggestion they enjoy a kind of testing phase where they determine if a potential mate is up to the rigors of the romance. :) Point is, don't separate too early or at the first sign of antagonism. Clearly you don't want incompatible fish to be locked in a death match and fish hiding in top corners or struggling to disappear behind a heater may be signs of a step too far, so monitor closely but give them a chance to be rambunctious.

I have found that two rock piles--one on each side of the tank--is helpful. Use a few rocks, flower pot shards, coconut hides, whatever gives them a place to hide. This helps to prevent rejected fish from trying to seek comfort in a rock pile claimed by a dominant fish. It also helps to net rejected fish. It gives them a place to dive for cover separate from the dominants and you can put in a tank divider, remove the rocks, and grab the fish while the pair is comfortably on the other side in their choosen space. This takes some patience and close observation so you know who you want to net, but if you watch purposefully I have found you can tell six fish apart by their markings. The downside is that the pair may decide your temporary hiding place is better than the pile you intend for them. Just be flexible here. Whatever place they choose for themselves is the one most likely to make them happy and spawn--at least that's the way I look at it.

I have not tried starting with adults. But my transcriptus juveniles have been very consistent in working themselves down to three fish. I get a pair, and one fish that is allowed to stay in the opposite rock pile. The pair is not aggressive toward the third fish, share space during feeding, but otherwise shoo it to its own side of the tank. I've seen this three times now. But I keep my Julies in species only tanks. Not likely to work in your tank if you remove the second pile of rocks and replace them with shells.

Patience is key. It takes some effort. Be flexible and creative. Fish have different personalities even within species; so a sure-fire method is just a place to start, not a guarantee. :) What works for the folks in the links above, or for me, or anyone else may not be the exact path your fish take. Be open to changing plans and enjoy the process. IME, it's worth it. Having a spawning pair and a couple generations of fry interacting makes for a really enjoyable tank. Beautiful fish with plenty of character and interest to reward your time.
