They should all school together with the occasional chasing, I would also look for some more paracyps.
Well, I made the plunge and they are actually smaller than 1"
. I gradually introduced them into that tank and I'm real happy with the method I used.
1) I put them in my largest net and had them introduced to the tank climate that way (submerged in the tank, in the net).
2) They were chasing their poo after a while, so I gave them a little dry food that is really, really small--and they ate -- I know--don't feed them at first, but I didn't know when they would be able to eat again once I released them into the tank.
3) I waited until fish bed time before I released them into the tank. I watched what you said would happen, except it was my little (very young) shell dwellers that did the chasing. Once I saw that they were cool--but not allowed in the shelly's "space", I put them all to bed with the lights off.
I learned about the light off trick from when I first started a Malawi tank--so I thought it wouldn't hurt.
The paracyp checked them out and I think once he realized what they were, he left them alone and started trying to start something with his female.
I wish they were larger, but I got a good deal--believe me, I looked and looked. I feel like I got at least 1 male out of 5 fish. Not great odds--maybe hand picked?
I don't want any more paracyps. I want more cyps. I found a place online that is supposed to get 5 more species on Wednesday. I'll see what he has and what he charges and go from there.
I hope my black calvus doesn't try to eat them. He is so shy he barely comes out of the cave to eat. I have to drop pellets practically on his head to get him to eat. He is small, but if he tried, he could do some real damage to the little fry.
Q: Why are the new cyp fry hanging out near the bottom? I thought they would be mid tank.
