I don't think it's a territorial dispute. Uriel(the angel) can't fit in any of the caves Moto hangs out in, and they always swim around with each other. She's just an aggressive b***h. Probably why she survived all of her brothers and sisters(Yes, every single other Black Belt in the group died)
crying And she doesn't force Gonzo(the spiny eel) out of any of the caves. I don't think she's concerned about territory at all. She's a 1.5 inch fish with a 30 gallon tank almost all to herself, and nobody to challenge her for space.
I still think I'm going to trade in the poor angel, despite how much I love it. It will already eat from my hands
crying I was thinking I'd get a Green Terror. I wanted one before I got the tank. I was gonna get one the day I got the spiny eel, but the GT's at my LFS were a bit too large and I figured they'd beat up on Moto too much, and the ones they had at Petsmart looked quite starved. I'd really hate to see Moto's impeccable fins get roughed up a bit by another aggressive tankmate, but I don't want to get a pair of shyer cichlids just to be her bitches.
I'm going to be adding some stones from a local river soon, so if for some reason it is territorial, the tank will be rearranged at that time. I'd like to not muss with it too much while I'm treating the ich.

Gonzo. He's a cutie. Still a bit yellow(every fish in Petsmart is. They must feed them some really piss-poor food), I expect he'll look a bit more natural after I get him to start eating. He won't touch frozen bloodworms. I gave him an earthworm, but it was too large for him to choke down(he made it about halfway before he gave up). So I'm going to consult my LFS about other live food options.
Also, if it matters to anyone, you can see in that photo I'm using a sand substrate. Once I take care of this ich I'm gonna get a plec to handle the carpet of algae growing on it(not pictured). The first plec I bought from my LFS died within 24 hours of bloat. And coincidentally after he died Uriel showed visible signs of ich. So he would have gotten infected anyway. Other than the whole carpet of algae thing the sand is working out pretty well considering it's the first time I've used it.
EDIT: Oh, and I should mention that Moto is infected as well, although she only has visible parasites on her dorsal and caudal fins. So it's possible they were both already infected when I got them.
