I've always been curious about the tinfoils. Do they have heavy bioload for their size? I think the lemon ones are nice looking.
they do have a decent bioload but they get to a foot long so kinda worth the extra water changes. I agree with

The yellow fin species you have is less conspecific aggressive than the Macrolepedotus species. I currently keep a single individual of both species in my 6 ft tank to avoid conspecific aggression. In my observation of Macro Chalceus in giant public aquarium tanks, they are always cruising solo away from one another. In small dealer tanks, juveniles I observed are always attacking one another with broken nose from jaw locking. Yes, keeping 6 or more individuals will spread out the aggression, but for fish that can reach 12 inch, you need a tank much bigger than 6 ft.
