As a matter of fact I do. Sorry I didn't see your post until now. Send me a private message and we can work out something.

Looking for Kryptolebias marmoratus eggs (PAN‑RS preferred)

Looking for Kryptolebias marmoratus eggs (PAN‑RS preferred)

Hello AKA members,

My name is A. Hirata, and I recently joined the AKA.
I am looking for Kryptolebias marmoratus eggs.

I am especially looking for the PAN‑RS line, but I would also be grateful for other stable lines such as BEL, HON, or DAN.

My purpose is long-term personal keeping and careful line maintenance.
I have no intention of selling or distributing the fish to others.
I simply want to keep this wonderful species in my own tanks and maintain the line responsibly for many generations.

If anyone has eggs available for sale or is willing to share some, I would be truly grateful.
I will cover all costs, including shipping.

Thank you very much for your kindness and support.

RE: Getting the kids into killifish

Hello David, If you're interested in some Notho eggs, I have several peat-incubated bags of N. korthausae Mafia Island TZN 08/4 that are ready to hatch. This is not the red strain, but has yellow and black stripes on the caudal fin. I cannot guarantee a hatch but my success rate is fairly high with these. N. korthausae are one of the easier beginner Nothos, and I'd be happy to send you a bag to try out. A good hatch will result in 50+ fry, sometimes a few hundred. Let me know if you're interested and I'll send them in the mail. The AKA discourages Nothos in their program for a free beginner pair of killifish because they are a little more challenging than non-annual fish, but I am happy to send these!

Getting the kids into killifish

Hey everyone,

I've kept a few nothos over the years as I live in Kentucky and it's hard to find killifish here. My 11 year old and 7 year old had started working with fry and have been doing quite well. The only problem we are having is the eggs came from Amazon and have abysmal hatch rates. We're out $60 with 3 fry hatched despite multiple drying wetting cycles. Aquabid seems to be all nonannual in the US and those just don't hit us the same as the gorgeous annual fish. Any tips or resources for finding eggs? I joined the aka as when I snooped around it said the sales forum often hosted eggs but it seems that was a little outdated.

Hey there,

Any chance you have any left?

RE: Water chemistry match

Ken Murch — Wed, 25 Mar 2026 23:15:19 +0000

Your water is moderate and suitable for most killifish species in the hobby. You can keep and breed 80%-90% of the species in common circulation with no changes. The more difficult Aphyosemion and Funduolopanchax species might benefit from softer more acidic water if you are having trouble breeding them. Species that have been in the hobby for many years are generally better adapted to a range of water parameters, versus wild-caught or F1 which may require more specific conditions. The local tap water where I am in Southern California is fairly hard and alkaline, and is objectively worse than yours for most killifish (but it's excellent for Nothobranchius). I raise most of mine in tap water whenever possible, and they breed well and do fine. I agree with your inclination to not mess with the water. Most species can adapt and tinkering with the water chemistry is high maintenance and risky for the fish. Large fluctuations can cause more problems than allowing the fish to adapt to stable (but not ideal) water conditions. If you do need to soften or acidify your water to get a fish to breed, do this gradually. This can be easily accomplished with tannins and does not require RO water, although RO can make it easier to get the pH down. I personally use catappa leaves or peat moss in a bag, but oak leaves would work and is locally available for many AKA members https://aka.org/general-tank-additives-oak-leaves-another-aid-to-conditioning-water/ If you do modify your water, you need to test it regularly because water chemistry will change over time. RO water is especially prone to swings because it lacks any buffers. Big fluctuations during water changes is a risk, and unless you are changing smaller volumes >20%. One trick is to keep your fish in bigger tanks (10 gallons vs 3 gallons) which stabilizes the water parameters and requires less frequent maintenance. You would also need to test and condition the water you use for water changes to match the tank conditions. I have lost fish to shock after changing out 'bad' water with 'clean' water because the change was too big of a shock. A final note on temperature. Some species such as Diapterons are temperature sensitive and prefer cooler water in the 60s. I can keep them alive in my tap water, but they won't breed for me. I gave up on keeping those because my tanks get to 78F in the summer months and they fade in the heat.

Good evening, Adam Thank you for your feedback and I am sorry I haven't replied to you sooner that the AKA and services provided by the AKA have not met your expectations. My lack of response and the tardiness of the AKA response is my fault and not a reflection on the AKA. I had family emergency that required me to be out of town and unable to answer emails. One of our AKA mentors, Rick Ivik responded to initial comments and sent it to me for my opinion, but I wasn't able to respond and please accept my apology. Both Sarah and Rick have reached out to you explaining the virtues of the AKA and all the new and exciting things we are working for the membership. Since your membership doesn't expire till 2027, you will have an opportunity to use the see and use the features and hopefully the improvements and changes you see will have you reconsider renewing your membership. Please feel free to contact me if you would like to discuss your concerns and feedback. Dave Hemmerlein

How do I cancel my account? I don’t want to be charged for a membership renewal and don’t want to worry about it.
