Apistogramma sp. "Diamond face"
Apistogramma sp. "Jutai"
(These two are the the same species, imported from a Peruvian exporter late 2009 and early 2010. They are the same species as Apistogramma sp. "Kelleri")
Distribution and habitat
Small jungle streams in the vicinity of the Colombian town Leticia.
Easy to keep.
Eats everything I offer.
Not much aggression.
Seems to be more shy when kept in smaller tanks, than when kept in larger ones.
This is a facultativ larvofil mouth-breeding species, just like Apistogramma barlowi.
I got 2 pairs of this species in late May 2010.
Two weeks after arrival, one of the pairs started breeding.......
The female used her mouth to move the larvae into a small pit in the sand, where they stayed until free-swimming! No signs at all of any mouthbrooding!
The week after, I noticed that the female of my other pair was chasing the male away in a rather intense manner. And she did that while mouthbrooding!
The differences between the two pairs:
The pair with the non-mouthbrooding female:
Tank: 85 liters (70x35x35 cm)
Other fish in the tank: 20 small youngsters of Nannostomus marginatus and one pair of Copella vilmae
Plants: Some floating plants, a couple of small Echinodorus,and some Cabomba aquatica.
Water: pH: 4,6 Conductivity: 102 microSiemens/cm Temperature: 26,7 degrees C (80,0 F)
Number of fry: 63 (!)
The pair with the mouthbrooding female:
Tank: 160 liters (100x40x40 cm)
Other fish in the tank: none
Plants: Some floating plants, a couple of large Echinodorus
Water: pH: 5,6 Conductivity: 90 microSiemens/cm Temperature: 25,7 degrees C (78.3 F)
Number of fry: 31
Both tanks have fine sand, wood, and peat filtered black-water.
The water movement is approximately the same.
The length of the day is 30 minutes shorter in the tank where mouthbrooding occurred.
The food was the same (Black mosquito-larvae and fresh BBS).
One would think that mouthbrooding would be more common in tanks with other fish, but here I could observe the opposite.
I never noticed any mouthbreeding from any of the males.
Around 2 month later, both pairs spawned again (with the first bunch of fry still in the tank). They behaved exactly the same way as the first time......
