I loved my spilurum, septemfasciatus and sajica when I used to keep them. I never got around to keeping Herotilapia multispinosa. I saw some today and was somewhat tempted but decided against it.
I used to keep Amphilophus robertsoni ages ago too but they were sold on and the bloke that had them lost them. I seriously loved those fish. I haven't seen any available for years sadly.
I sold my breeding pair of septems because I couldn't raise them in a 5ft American community tank and had no space to raise the young. They bred for me all the time and were moved on to another guy and he never got them to spawn.
H.nicaraguense parrots are amazing. I had the most beautiful female once. I used to feed them on Discus colour enhancing granules and the green and orange on her was out of this world.
