...are they hybrids? I bought a group a couple of months ago for my mbuna tank. It's the albino yellow labs, and white top haras. I never thought much of it when buying them, but after seeing them in the tank (I've only ever had regular old labs, this is my first time having the albino variant) I've started to wonder if they're hybridized to get albino into the mix? They're aggressive! Yeah, of course, all mbuna are aggressive, but anyone who knows mbuna knows that labs are generally fairly mild-mannered for mbuna. These guys are freaking monsters. I have no aggression issues with the group of hara, even with about 5-6 males in a group of 11 fish from what I can tell...they bicker and chase a bit of course, but it's pretty low key for mbuna everyone is generally pretty happy. But the albino labs are brutal. Two of them seem to have taken over the entire tank, claiming one end of the rockwork each, and they're pretty horrid to the others. Most of the the others are hiding in corners, under the filter out pour, behind the intake tube, etc. They leave the haras to do their own thing but these two dominant labs are terrorizing the other poor labs. I'm thinking I'm going to have to pull them out and maybe swap to regular Lions Cove labs to get my yellow fix in the tank, which is a pain.
