Help ID this Killi

[TBoss]

Caught these killifishes by chance on a hiking trip in Singapore. Yes. Wild. In Singapore. Anyone can help me ID them?

*Sorry I will not disclose the location to protect them from over poaching.

Those are Aplocheilus lineatus. Pretty killies. You should start breeding them. They are not so common compared to the golden variant which are sold as Golden wonder panchax.

Another thing about these fishes. Make sure their tanks are covered and no small fishes as tankmates. They are excellent jumpers and have a rather large mouth. Good luck with these fishes but Singapore is not within their native range.

Thank you Shi Xuan. I'm new to Killifishes and only started trying them recently. I was lucky enough to stumble upon them from info from my girlfriend. I have a tank with alot of floating plants and a cover. So I hope it's enough to stop these superb jumpers.

Yep, these are wild-type striped panchax (Aplocheilus lineatus), like Shi Xuan mentioned. The golden killifish is much more common in the shops, but it's an artificial strain.

It's interesting as this species is not native to Singapore; our only native killifish is the related blue panchax or whitespot (Aplocheilus panchax). There's a paper documenting the presence of breeding populations of striped panchax in Bukit Batok and the Botanic Gardens, it would be interesting if your fishes came from yet another population.

Care should be relatively straightforward: they'll take both prepared & live foods, and your floating plants and cover should help reduce the tendency to jump. However, they might nip at the fins of other fishes, or target invertebrates like shrimps. They're not territorial, but adult males can be quite aggressive towards each other. You'll be amazed at how wide they can open their mouths!
