I asked a US Homeland Security guy at our local (Canadian) International airport to have a look at this question. He told me all egg imports into the US were subject to the same permits as live fish.
That being said, I doubt it's worth even looking up for the Customs guys. It's not like we're doing a multi-million dollar business in australe eggs. I wouldn't expect the average reasonable pro working at a border to care about fish eggs, although they could do a double take if they opened the package and saw a baggie full of peat...

I first saw the Yabassi fish at least ten years ago, as nototaenia. It was distributed as cf nototaenia Yabassi, and as is usual, it vanished after one generation. I was helping the importer unpack, and I can tell you a bag of 300 adults held up to the sunlight may have been one of the most colourful things I've ever seen.

It's a great fish. If you like and want more, it's easy to breed. The first time I had gardneri I put my pair into a heavily planted tank and left them for ten days. I removed the adults and within a week I had 35 relatively fast growing fry.

In the AKA, you will see an emphasis on location names. You might see F gardneri Akure (or Jos Plateau, Makurdi, etc). We have the luxury of often knowing where our killies come from, and since there are often genetic differences between different populations isolated from each other, the location name serves to help us keep the genetic forms distinct. There are a lot of different "gardneris" , all of which are great fish.

Rainwater was my source of soft water for several years in my old house. I tested it regularly and was able to breed a lot of killies and dwarf cichlids in it. In the short term, there never was a problem, as long as I respected the "wait for the roof to roof to be cleaned off" rule Barry suggested. In the longer term, the unpredictability of rain was a problem, as I consider a key to breeding killies to be environmental stability. I could control temperature and lighting periods in my fishroom, but droughts or periods where we had lots of short showers and no sustained rain affected my water changing regime. Plus I once got to hear my daughter refer to the weather as a "good forty gallon rainstorm."...

When you get the fish, try going with one species in the tank, Watch them, and you'll see why. There's plenty of beauty in a killie, and the choice you've made (misaje) is an excellent one. There's also some intriguing behavior to be seen, and it just won't show in a 10 gallon community. Killies can be extremely interesting when kept on their own.

Wow, this is quite a purchase. You have some species listed that a longtime, experienced killiekeeper would find challenging.
The thing is, the question you ask is enormously complicated to answer. If I were you, I would start googling the species one by one, and what what you can find on their care. One thing you will find is that killies are quite different, from species to species. There are very few blanket statements I could offer that would apply to all killies. If you like digging into questions, you have an amazing time ahead of you...

Well, a huge storm and a tree down on my power line in August did my brichardis in. It was very hot, and I had just moved so everything was poorly set up in the fishroom. I spent years trying to get them, and this is frustrating. Best of luck with them - they are beautiful.

I have been lucky enough to find some of these, but am wondering if I can get any tips to succeed with them. I am keeping them in a planted tank with good filtration, moderately hard water and a temp of 21C.

Maybe I'm joining in too late for anyone to bother reading, but a very effective alternative for breeding what's now "Poropanchax" normanni is to put a group or pair into a planted container (a rubbermaid 3-5 gallon is ideal and cheap) and leave them for a week, feedng them well but not excessively. You can put in hornwort, java moss or acrylic mops, but normanni will also produce fry in tanks with gravel bottoms and nothing else. Aerate and do a water change. Remove the adults to their usual tank and watch the surface of the breeding tank. One pair might get you 10-15 fry in a week, and if you can land three or four more adults, you could find yourself with 50 or more fry.

I've had successful spawnings from 66 to 78 degrees F, but I haven't had great success unless the container with the eggs had water movement (an airstone, a sponge filter, or even a bubbling hose).

I'm glad it worked out. Killies always look bad when they arrive, but generally, they recuperate well. Personally, I don't worry about pH in such a situation, and use no products but a dechlorinator on them. Later, if you get a fancy set-up, you can modify water, but if you start with all the pet shop products then you are bound to offer inconsistent conditions to your fish. Put on a cover that's tighter than you can imagine. The more you like a killie, the more likely it is to jump out...
