Neolamprologus cylindricus
Remarks: Neolamprologus cylindricus is a torpedo-shaped rock-dwelling fish from Lake Tanganyika. These fish love rocky formations and are rarely seen more than a few inches away from one. Males will spawn in a female’s cave, producing up to 250 fry in one batch.
Tanks should be furnished with several piles of rock, reinforced to prevent tumbling if digging occurs. Tankmates include other Neolamprologus species, as well as Julidochromis, Altolamprologus, and Cyprichromis. Sexing is difficult, so a group of 4-8 juveniles should be raised together if breeding is desired.

Wendy Nash –
The fish are active and interesting to watch. They prefer rocky areas and stay close to them. I added several rock piles and they’ve been thriving. Good for a community tank with similar species.
Heather Lewis –
They are hard to sex and need a group of juveniles to breed. The tank setup must include stable rock formations. They are peaceful and stay in their caves most of the time.
Alison Morrison –
I’ve kept them with Julidochromis and they coexist well. The fry production is impressive when a male and female are paired in a cave setup.
Diane Sharp –
The fish are active but require a lot of space and proper rock structure. I had to reinforce the rocks to prevent them from falling. Not for beginners.
