As with many annual-type killifish, it is a specialist species that rewards attentive care, a varied diet, and stable conditions. The exact adult size, water temperature, and pH can vary by line and source, so please \u003cstrong\u003everify with your local water\u003c\/strong\u003e and check the needs of your specific stock before purchase.\u003c\/p\u003e\u003cp\u003eThis species is ideal for hobbyists looking to keep something a little different from mainstream community fish. It is best appreciated in a well-planned setup where water quality is excellent and tank mates are chosen carefully. We supply juveniles at approximately \u003cstrong\u003e2.5 - 3.5 cm\u003c\/strong\u003e, giving you the opportunity to grow them on and enjoy their developing colour.\u003c\/p\u003e\u003ch3\u003eWhat makes this fish special?\u003c\/h3\u003e\u003cp\u003eKorthaus Notobranch Red is part of the killifish group, a family well known for seasonal life cycles, vivid males, and fascinating breeding behaviour. Even when kept outside dedicated breeding projects, these fish are appealing because of their colour, shape, and active feeding response. They are not the best choice for a brand-new aquarium, but they can be highly rewarding for keepers willing to observe, plan, and maintain consistent conditions.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFreshwater specialist killifish\u003c\/li\u003e\n\u003cli\u003eCompact size, sold as juveniles\u003c\/li\u003e\n\u003cli\u003eBest kept in a calm, well-maintained aquarium\u003c\/li\u003e\n\u003cli\u003eIdeal for aquarists interested in breeding and behaviour\u003c\/li\u003e\n\u003cli\u003eWater values should be checked against your local supply\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTank Setup\u003c\/h2\u003e\u003cp\u003eBecause this is a specialist freshwater killi, tank planning matters. A mature, covered aquarium is strongly recommended, as killifish can be alert, quick, and sometimes prone to jumping. A secure lid also helps reduce evaporation and keeps water conditions more stable. For a single pair or a small group, start with a tank of at least \u003cstrong\u003e40 litres\u003c\/strong\u003e; larger is always better if you want to provide more space, better stability, and more territory options.\u003c\/p\u003e\u003cp\u003eUse a soft, natural layout with plants, fine substrate, leaf litter, and shaded areas if you want to encourage natural behaviour. Floating plants can help reduce bright light and make the fish feel more secure. Gentle filtration is usually preferable, as these fish do not need violent water movement. Good oxygenation and clean water are important, but avoid strong currents that may stress them.\u003c\/p\u003e\u003cp\u003eSince precise temperature and pH figures were not supplied, we recommend you \u003cstrong\u003everify with your local water\u003c\/strong\u003e and match the fish to a setup that can be kept consistently within the appropriate range for the species. Sudden swings in temperature, pH, or water quality should be avoided. Regular partial water changes and careful maintenance are essential.\u003c\/p\u003e\u003ch3\u003ePractical setup tips\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eUse a tight-fitting lid to prevent jumping\u003c\/li\u003e\n\u003cli\u003eChoose mature filtration and stable conditions over flashy décor\u003c\/li\u003e\n\u003cli\u003eInclude plants or spawning material if you plan to breed\u003c\/li\u003e\n\u003cli\u003eKeep lighting moderate rather than harsh\u003c\/li\u003e\n\u003cli\u003ePerform small, regular water changes rather than infrequent large ones\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDiet \u0026amp; Feeding\u003c\/h2\u003e\u003cp\u003eKorthaus Notobranch Red is best fed a varied carnivorous diet. Killifish generally respond very well to live and frozen foods, and these usually help maintain colour, condition, and breeding readiness. Suitable options commonly include bloodworm, daphnia, brine shrimp, mosquito larvae, and similar small meaty foods. High-quality prepared foods may also be accepted, but variety is important.\u003c\/p\u003e\u003cp\u003eFeed little and often rather than overloading the tank. Because killifish can be enthusiastic feeders, it is easy to give too much. Small portions once or twice daily are often enough for healthy adults, while juveniles may benefit from slightly more frequent feeding. Remove excess food promptly to protect water quality.\u003c\/p\u003e\u003ch3\u003eFeeding good practice\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOffer varied live and frozen foods where possible\u003c\/li\u003e\n\u003cli\u003eUse quality prepared foods as part of a balanced routine\u003c\/li\u003e\n\u003cli\u003eAvoid overfeeding, especially in smaller aquaria\u003c\/li\u003e\n\u003cli\u003eAdjust portion size to the fish’s activity and body condition\u003c\/li\u003e\n\u003cli\u003eKeep water clean after feeding to prevent waste build-up\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTank Mates \u0026amp; Temperament\u003c\/h2\u003e\u003cp\u003eThis species is generally best described as a specialist freshwater fish rather than a classic community species. Males can be territorial towards one another, especially in smaller aquaria or during breeding. The best approach is usually to keep one male with one or more females, or to keep a carefully managed group in a suitably sized tank with plenty of visual barriers.\u003c\/p\u003e\u003cp\u003eGood tank mates are calm, similarly sized fish that will not outcompete the killifish for food or nip fins. Avoid fast, boisterous, or aggressive species, as well as large fish that may see the killifish as prey. Very tiny fish may also be at risk if they fit into the mouth of a larger specimen.\u003c\/p\u003e\u003ch3\u003eSuitable companions may include\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSmall peaceful tetras, if water values are compatible\u003c\/li\u003e\n\u003cli\u003eRasboras of a similar size and temperament\u003c\/li\u003e\n\u003cli\u003ePeaceful bottom dwellers, where appropriate and compatible\u003c\/li\u003e\n\u003cli\u003eOther non-aggressive species that do not crowd the surface area\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eBecause precise water requirements were not supplied, compatibility should always be checked against your local water and the needs of any fish already in the aquarium. In general, a calm species-only or carefully planned community tank is the safest route.\u003c\/p\u003e\u003ch2\u003eBreeding\u003c\/h2\u003e\u003cp\u003eBreeding is one of the most interesting parts of keeping \u003cstrong\u003eNothobranchius\u003c\/strong\u003e killifish. Many hobbyists keep them specifically for this reason. Courtship can be fascinating, with males displaying rich colour and active behaviour while encouraging females to spawn. Depending on the exact line and conditions, eggs may be laid in spawning media, fine substrate, or dense planting. Because this is a specialist fish, breeding methods should be matched to the stock you have and the advice provided by experienced keepers or the original source of the fish.\u003c\/p\u003e\u003cp\u003eIf you intend to breed them, set up the aquarium with spawning areas and keep the pair or group under careful observation. Remove any eggs or spawning material according to the method you are following. Always verify the appropriate incubation and rearing method for your particular stock, as annual killifish can be especially sensitive to incorrect handling.\u003c\/p\u003e\u003ch3\u003eThings to remember when breeding\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eProvide gentle shelter and spawning material\u003c\/li\u003e\n\u003cli\u003eUse high-quality food to condition adults\u003c\/li\u003e\n\u003cli\u003eMonitor water quality closely\u003c\/li\u003e\n\u003cli\u003eCheck the breeding approach for your specific line\u003c\/li\u003e\n\u003cli\u003eRaise fry on suitably small, nutritious foods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHealth \u0026amp; Common Issues\u003c\/h2\u003e\u003cp\u003eLike most specialist fish, Korthaus Notobranch Red thrives when water quality is stable. Stress is the main thing to avoid. Poor water conditions, unsuitable tank mates, and irregular feeding can all weaken the fish and make them more prone to illness. Because these are often kept in smaller aquaria, filtration and maintenance are especially important.\u003c\/p\u003e\u003cp\u003eCommon issues include fin damage from rough tank mates, loss of condition from a poor diet, and stress related to unsuitable water parameters. For this reason, we strongly recommend keeping the tank covered, feeding a varied diet, and monitoring the fish closely during the first weeks after arrival. If any fish show signs of clamped fins, refusal to eat, rapid breathing, or unusual hiding, check water quality first.\u003c\/p\u003e\u003cp\u003eAs the exact temperature and pH range were not supplied, please \u003cstrong\u003everify with your local water\u003c\/strong\u003e and use your own test kit to confirm conditions before and after introduction. Clean water, low stress, and a sensible feeding routine are the foundation of long-term success.\u003c\/p\u003e\u003ch2\u003eBuying From Us\u003c\/h2\u003e\u003cp\u003eAt Tropical Fish Co, we aim to supply healthy, well-packed fish that are ready to settle into your aquarium.
