Hi Simon! It was in fact all one colour, and it's mid-section changed to clear. In general, shrimp activity has diminished significantly with many hiding, lethargic, refusing to eat. It is really noticeable compared to my other tanks and I sense death is imminent.. I have not been able to remove it as I unfortunately don't have another cycled tank for quarantine. It is only in the breeder box for observation currently. My apologies I forgot to post pH, it is 7.4. There is a HOB filter which should provide some aeration, as well as the egg tumblers with air stones. I was previously feeding hikari crab cuisine every two days but have since switched to soybean husks since yesterday; so I can leave them in, in case they get hungry. I've noticed none of the shrimp will come to eat and was afraid of fouling/ammonia spiking. Only snails are eating it. I've also made some shrimp kandy feast (awesome recipe jayc) and other tanks will maul it except this one. The eggs have eyes now! Which coincide with other berried females' eggs, so hopefully they all hatch close to each other ? A friend suggested dosing h2o2 at 0.3ml/L daily, for 1 week. Would you condone this?

I use a few different breeder boxes, and while none of them are perfect, they seem to do the job for me. I don't have any idea what models or brands they are, besides one - the Aqua One Mini Float. I bought it for endlers and shrimp, and I doubt it would work for guppies, mollies or any other larger livebearers, since it is (as the name would suggest) pretty small. It's hard plastic, which I like (for usability), the suction cups kind-of suck, although it does have two compartments on either side that hold air, so it won't sink if the suction cups come off. It's a great size for my 5 gallon tank. My problem is that the gaps are too large for shrimplets. I think there should be some alternative option that has a very fine mesh (like in a shrimp net) that can be attached over the areas that have water-flow holes. It also comes with a removable divider for fry seperation. I do prefer breeder boxes with a divider option. I also have 2 of those rather common large mesh ones, that pack really small and have a net that goes over the hollow-cube structure. One has 2 dividers (so you can subdivide it into 2, and have a baby-catcher underneath still) which I found very useful when I was breeding lines with 1-2 males and 2 females, as the females would drop their fry around the same time. So I think the metacube idea is a really good one. There are a couple reasons I prefer hard plastic (with a fine mesh attachment possibly) over mesh with plastic scaffolding (like this) - firstly, the plastic ones are easier to move when you remove the fry. I have on multiple occasions accidentally left a fry in the mesh one without realising. Luckily I noticed in time, and I haven't had any deaths from that. Secondly, there are slight gaps between the mesh and the scaffolding, and the fry have a tendency to get stuck in those gaps. If I don't notice, there's a fair chance I could lose some of those fry. I also have problems with the mesh ones getting algae on them. If the hard plastic gets algae, I can easily rub/scrape it off. The mesh just does not let go of algae though, and it can be a bit of an eyesore (in addition to how ugly the mesh ones already look). If I try to suck it off with a syphon (just cuz) the fry get sucked into the net and stuck. I hope that's helpful. I do realise it's a massive mess of text. To sum it up, the things that are important to me as a shrimp, endler and guppy breeder are the following: Clear, hard plastic box Divider option Safe for baby shrimp Has a possibility to use multiple beside eachother - possibly interlock GOOD suction cups (like Eheim ones) Smaller size Works with and without a lid No places for fry to get stuck. Cheers, Crabby.

The Ziss and Metacube breeder box I have does not come with a divider for the eggs to drop down away from the parents. But, yes, that would have been a nice feature to have. The divider needs to be removable however.

Hi guys, Have been having issues with my yellow neocaridina tank this past month, from a berried female death, general inactivity in the past 2 days, to this discolouration in the body (yellow to translucency). I am afraid the colony will collapse soon if I leave as is. Parameters: Ammonia 0, Nitrites 0, Nitrates ~5-10 KH: 3 GH: 7 TDS: ~205 Temperature: 23-24 What would you guys diagnose this as? Differential being muscular necrosis? Help much appreciated, thank you!
