Click on list to left for more detailed information on each population.

Telemu - Background colour on body & fins blue/green. Small red spots on body & all unpaired fins. No outer marginal bands or lines in unpaired fins.
This one is a little different to other populations.

Okwoga. Situated at the headwaters of the Cross River, southeastern Nigeria.

Boulenger 1915 also lists collections from :-

• Bendi District, Cross River (collected by Major W.A.C.Cockburn).
• Old Calabar (Collected by Mr.J.Paul Arnold).
• Swamps between Agwarba & Awka, Lower Niger (Collected by Capt.R.D.Gard'ner.

Udi mountains in the upper Cross River drainage system, northwards into the lower Benue River drainage of eastern Nigeria.

Swamps, small pools & swampy areas of brooks in humid rainforest & savannah.

Fairly easy to seperate from other sub species by having a very spotted body on a green/blue background. Anal fins are spotted & have no outer marginal band.

The Lafia population can be distinguished by a more greener background colouration to the upper body.

First described as Fundulus gardneri by G.A.Boulenger in 1911. The 3 type specimens were collected by Captain R.D.Gardner at Okwoga, south eastern Nigeria & measured 60 mm in length. In the same year he described Haplochilus brucei collected by Major G.E.Bruce from a pool at Udi from the Cross River drainage . Later (1915) he considered brucei to represent a synonym of gardneri.

Boulenger gives the following collectors / locations in his 1915 Catalogue.

• 1-3 (Types) Collected by Capt. R.D.Gard'ner at Okwoga, situated at the headwaters of the Cross River.
• 4-11 (Types for H.brucii). Collected in a pool at Udi in the Cross River basin by Major G.E.Bruce.
• 12-16. Collected by Major W.A.C.Cockburn in the Bendi District, Cross River.
• 17. Collected in Old Calabar by J.P.Arnold
• 18. Collected by Capt. R.D.Gard'ner in swamps between Agwarba & Awka, Lower Niger.

In 1976 Wright & Roberts collected a population near the Catholic mission at Lafia.

History of the synonym Haplochilus brucii Boulenger 1911

Boulenger described the sp. in 1911 from 8 specimens collected in a pool at Udi, Cross River drainage. He later ( 1915 ) considered the sp. as a synonym for gardneri.

Easily spawned. If you can't breed these it's time to hang up your mops!

Eggs are laid in top & bottom mops which can be collected & stored in a seperate container. They can be water stored for 14-21 days or laid on wet peat where they can be left to incubate for 4 weeks (some will go to 6 weeks). Fry will eat newly hatched brine shrimp as a first food. Growth rate rate is quite fast with sexual maturity showing at around 5-6 weeks.

A blue phase fish was tank bred from yellow phase Nsukka. This is not unusual for gardneri.
