How to take care of Killifish?

I am a beginner at breeding, i looked it up for a year with guppies but then there was a fault, my 5 local pet shops don't take Guppies in from the public! So i found killifish, i would like to know all of the basic information for caring for them, breeding and there tanksize (min) and some other information you may want to add! Thank you

    Killies have been described by a cichlid keeping buddy as "guppies that lay eggs." That is a neat summery and taxonomists would even say that our hobby livebearers (there are somewhere over 100 livebearing aquarium fishes in 100s of strains) and killies (of which these are over 1,000 species, strains & color sports) are rather closely related. Feeding, care & housing can be similar for similar sized fishes, though breeding water may be rather different in some cases.

    A caution first on selling to pet shops, though the situation may be different in the UK from the US. Pet chains are often limited to a computerized inventory of 150 to 200 species and are forbidden to take fish from hobbyists. Independent stores are more flexible, but talk to their manager first. Most just give store credit. A few will trade for other fish or products. Rarely some will pay cash for fish.

    There are also aquarium clubs & killifish clubs around the US, UK & the world. These are great sources of information, breeding stock, food cultures, plants and even a modest market for extra killifish. Google your city or state or district and Aquarium Societies.

    You might also look around, maybe doing a Google image search for plant spawning species in genus like: Aphyosemion, Epiplatys, Scriptaphyosemion, "Chromaphyosemion," "Diapteron," Aplocheilus, Pachypanchax. If you like schooling fishes, search for the social lampeyes'

    And then there are the annual killies, fishes that include about 30% of the known killies. They live un temporary waters, hatch out & grow like crazy. They lay eggs in the mud and usually perish in the dry season. Their amazing eggs can survive in the clay soils for a year or more. You might be best off trying a plant spawner first.

    Some killies are drop dead beautiful. Some are typical "little gray ditch fish." Males (better behaved w/o females to court) will do fine in a community tank if they can't swallow anyone. A lot of times, as the killie bug bites, we wish to try breeding them. Most of the fry can take newly hatched bbs (baby brine shrimp) if it is harvested a few a few hours after hatching.

    Fp. gardneri are a little aggressive, but could be called the guppy of the killies.Typically they and almost all killies are bred in single-species tanks. We try very hard not to mix strains because the specific strains may never be able to be collected again.

    A killie with just a popular name or scientific name and no collecting location or code is an aquarium strain. They still shouldn't be hybridized with other species, but there isn't the compulsion to keep them from others in their strain or species. Yellow gardneri for instance. Ah, and they sell for less usually at auction.

    They can be bred is a bare tank (with sponge filter and acrylic mop and the eggs picked in the evening. They will leave fry in a well planted tank (like you 1st guppy tank). Adults can also be fed well and pulled from that planted tank after a couple of weeks.

    Some like A. australe don't lay eggs if the water has too much mineral in it. De-mineralized water can be added gradually until they are laying viable eggs.

    Recently another question on feeding killie fry came up. This may be useful for you:


    There are lots of killifish eggs on www.aquabid,com but they will probably run $5 to $30 PLUS shipping! The American killifish Association also has Fish and Egg listings and an auction on-line. Local clubs have meeting mini-auctions that often sell eggs for a couple of bucks or pairs of adult killies for $5 to $8. It may be easier to get a pair, as suggested, and let them produce eggs.

    If a member of my local group, the Chicago Killifish Association, were to call me up and ask for a Daphnia culture start, eggs (I'd have to set up a pair with an acrylic mop or gravel vacuum a tank through a fine-meshed net) or a plant start and are just willing to drive over (a young man and his Dad were here a couple of weeks ago) if they will take the trouble (and gasoline) to get here and maybe will pick the eggs, I figure they have "shown willing" and don't usually charge for them. Some others are like that.

    I hope you are able to get a pair or eggs and really enjoy keeping killies. If there is a particular species you are interested in, you might make further inquiries about them here or via the references suggested.

    Killifish Care

  • 8 years ago

    It will depend on what kind of killifish your looking at, there are alot out there. If your talking about the golden panchax(wonder) then you'll need a tank about 30gallons+ and they are natural predators with giant mouth...so they'll eat anything that will fit in there. The other killifish which are smaller like the Gardneri panchax and can live in a smaller tank like a 15-20gallon min and usually works well with most fish except gourami's and betta's.

    Used to be this a type of silly fish in a teabag box set things. I'd try a grow them up just a little within the smaller tanks so set up a few them. Then i might think the 95 can be first-class. Goodluck but i would not count on them to outlive very long at all.

    Singapore has a vibrant record and varied ethnic quarters to discover, combined with many family-friendly attractions and wonderful community spaces that make visiting this somewhat advanced town advantageous so begin planning your vacation, start with Hotelbye . In Singapore you are able to visit the world's biggest massive statement wheel, the Singapore Flyer. Another lovely place you can visit in Singapore may be the Bay East Garden. Bay East Garden is the right area for enjoying the lively vegetation and escaping the town bustle for a moment but, in the exact same measure, you are able to enjoy the Cloud Forest Dome to start to see the world's highest interior waterfall and learn a little about biodiversity.

    There might be 50 different correct answers to your question. I'd advise looking around for an inexpensive, basic introductory book or try the American Killifish Association web site. Killies are a very interesting and diverse group of fishes. You need more knowledge before you begin asking questions.
