Hey zabelkid, nice tank, I do love them mbuna.
Your aquascape isn't entirely unlike mine in my 125, which is a nice footprint for mbuna.
I didn't catch your Cyno's in the video, but did notice that it appears you're keeping just 1-2 of each species, is that true? Is this an all-male tank perhaps?
I have a quad of Cyno. afra "Cobue" that have only spawned one time; I'm growing out their 6 juvies now, which are approaching the 1.5" mark.
I also have Cyno. afra "hara" white top that are wild-caught, but none of my females are big enough to spawn yet.
I'm trying to decide whether I can get another Cyno. into my tanks; maybe a Jalo Reef.
What type are you specifically looking for?
