Blue Lyretail (Gardner's Killi)
Fundulopanchax gardneri
The Gardner's Killifish (*Fundulopanchax gardneri*) is perhaps the most robust and easiest killi of all to keep and breed, perfect for beginners to the genus. The male is a dazzling spectacle: metallic blue-green body densely spotted with crimson red, with yellow fins bordered by vibrant red stripes. Females, as typical in killis, are a modest dotted grey-brown color. Beyond its brazen beauty, its huge merit is extreme adaptability: it is a 'semi-annual' killifish that tolerates a wide range of water conditions.

Description
Longevity:
Unlike strict annuals (*Nothobranchius*) that obligatorily die within 10 months due to accelerated aging, an *F. gardneri* kept in cool tanks (maximum 24°C / 75°F) and not overfed, can easily live 2 or 3 years in the aquarium.
Local Variants (Lokalformen):
Being widespread in West Africa, there are countless geographical variants collected by enthusiasts (e.g., *Nsukka*, *Lafia*, *Makurdi*, *P82*). The differences concern the intensity of the light blue or the thickness of the red/yellow bands on the fins. NEVER mix variants from different locations in the same aquarium to avoid hybridizations that would ruin the integrity of the strain.
Care and observations
Secure Setup:
Compared to microscopic annuals, this is a "massive" and stocky killifish. It requires a real aquarium, heavily planted, with a dark bottom (sand or Catappa leaves). The absolute imperative is the lid. The *F. gardneri* has the ability to find unthinkable openings to jump: cover even the cable holes with sponges.
The Convenience of the Semi-Annual:
This species lives on the ecological border between permanent swamps and streams that dry up. Therefore, it is "semi-annual" (or *switch-spawner*). The aquarist can choose: they can insert floating green acrylic wool "mops" in the tank; the fish will lay sticky eggs in them daily, which will hatch directly in the water after a couple of weeks (without having to dry anything). Or, they can place peat on the bottom and simulate a drought by collecting it and storing it damp for a month before wetting it.
Bold Temperament:
It is not the classic shy killifish that hides. Males will patrol the tank, chasing females and showing off (displaying) in front of the glass as soon as you approach. Just make sure you have 2-3 females for each male, as his continuous amorous attentions are stressful.
Fish profile
- Temperament
- Vivace, audace e moderatamente aggressivo. I maschi ingaggiano combattimenti per il territorio e le femmine. Non sono timidi come gli *Aphyosemion* e spesso strapperanno il cibo direttamente dalle pinzette dell'allevatore.
- Diet
- Micro-predatore. Onnivori in acquario. A differenza di molti killi delicati, i F. gardneri sono golosissimi: accettano avidamente cibi secchi di buona qualità, ma per mantenerli in salute e riprodurli vanno regolarmente somministrati chironomus, tubifex, enchitrei (grindal) e larve di zanzara.

- Reproduction
- Semi-annuale / Switch-spawner. Il loro grande vantaggio è che possono essere riprodotti in due modi: o si lasciano le uova nei 'mop' di lana in acquario (schiuderanno in 2-3 settimane in acqua), o si raccoglie la torba sul fondo contenente le uova e la si fa seccare/riposare per 3-4 settimane prima di bagnarla di nuovo (metodo annuale).
- Compatibility
- Tenerli con pesci pacifici della stessa taglia. Possono mordere le code dei pesci con pinne a velo (es. Guppy maschi) o ingoiare pesciolini troppo piccoli (es. Boraras brigittae). Ottimi con i Corydoras e piccoli Loricaridi.
