Lake Tanganyika Species • Temporalis shell

[Merciless]

Hello,

Couple Quick questions about the Temporalis shell. I just received 8 of them. I have at least 3 males (they are larger) and they are mouth locking but nobody seems to be getting hurt. They are currently in a species only 40G breeder but I will be moving them to a 75G.

Should I not worry about it and just let them work it out in the 75G? Or would I be better off removing two of the males in hopes the other will mate with one of the others, assuming one is female.

Not sure if this behavior is the norm, or if they are like Gold Ocellatus and will end up killing each other.

Do you know if the color is change (light to dark) is once they become adults, or is just a difference depending on where they were located in the lake?
