I have gone through 5 emerald crabs and currently only have 1 small ruby. My Dottyback thinks they taste really good. The only reason the Ruby is probably still around is because she is small enough to hide.How many emerald crabs do you keep in there? I love them for algae control except when they get too big. That is when I see them going after fish with more determination.
My largest I ever had was in this tank, easily 2in wide body. I never considered sexing the crabs. Seems like such an easy thing to do with us boys that grew up on the Gulf.I am not sure of the measurement, but it was one of the largest I have seen in aquaria. It would hang on the rock and claw after the fish as they passed by. I fed the tank enough I am sure. I guess they get a desire for fresh meat when they get older. I heard from Joey at Aquarium Central that one sex is more aggressive than the other. Is it the males? I have a hard time telling them apart.
Not yet, but that is part of my plan going forward. My area I would grow the chaeto is covered by my RO/DI reservoir sits on top and would just way to complicated to work with. SO! My eyes are wide open looking for a eye appealing RO/DI reservoir that I can have on the outside of my stand which would greatly upgrade the possibilities of my sump. I have my lighting all sorted and ready to order. Just finding something to hold water that can blend in with decor is a tough one. I don't want to drop $200 on a bucket of water if you catch what I am saying.You have chaeto in the sump? If not, I have some I can give you.
What about rolling your own? Get a cheap tubberware container for the size you need and box it out with some craft work. You can go plywood stained or painted, or hit a craft store and get creating with basketweave or something else. There are many ideas out on the web for some creative ATO options.Just finding something to hold water that can blend in with decor is a tough one.
