Ok, I'm convinced. I think I'm going to add to my setup only a couple of Apistos. I've been atracted by the A. cacatuoides and the A. eunotus. I have heard of the gregary behaviour of the A. eunotus, just like some Lamprologus. Can someone confirm this? However, I never saw this species, is it colourful and cute? Maybe I decide to buy the A. cacatuoides. What do you think if I add a pair of Nannacara anomala? I've read somewhere they are very peaceful. Fredrik asked which killies I'm thinking of. Good question :). I don't know because I never had killies too. Which ones do you suggest? Currently, I am trying to adjust my water parameters. I have a pH of 6.0-6.5 (do you advise a pH inferior to 6?) and a total hardness of 3ºgH. I think I'm not going to make more changes.
