Hello all,
I'm very new to looking after any type off fish but i decided to start at the deep end and look after a reef aquarium and on a small scale, its only 54 litres with 10 kilos of live rock and an 1 1/2inches of live substrate at the moment, i do intend to add more rock, at the moment i only have an emerald crab and red legged hermit crab plus a few corals and sponges which came on the rock i also have loads of small creatures, bristle worm x1 , death plague x1, other things i havn't identified yet but i'll post some pics soon, My main reason for joining the forum is my emerald crab gave birth to 50-100 babys, i turned all pumps and skimmers off, added a air stone and 36 hours later i can still see a few alive the rest i can't see and have no idea where they have gone any ideas on how to care for them cus at some point all my pumps need to go back on, nitrate levels are rising fast and i can't have that my water quality was perfect, help!!!!

Hi and welcome to the forums..

Your best bet is to remove them into a smaller grow-out tank, as you do need to get the pumps back running on the main system. Leaving them off is not good the tank as a whole.

Feeding wise, you'd need to setup rotifiers / feed plankton..

All said and done, if they are left in the tank, they will become food.

Hope that helps.
 
Thanks, will it not benefit the other inhabitants of my tank to leave them in and see what happens???
 
Not that i know of, no...sorry...i know plenty who have had spawns, but never successfully raising..As i am aware, there are many online docs about raising lysmata shrimp, and i would say the same principles would apply to raising crabs..
 
Thanks very much i'll have a read an see if it helps, hope they survive perhaps i might be able to help people in the future, but i have a good video and pics of her releasing her eggs and eating some from her pouch so i'll post soon as, the tanks only been up and running for just over 6 weeks, water quality was spot on no nitrate, nitrite, phosphate or ammonia and all but calcium were good.
 
Babys ahoy

Well its been just over a month and i have had no sign of any babys in my tank but in the last two nights i have spotted at least 1 baby crab per night, the first night i spotted a small crab with transparent legs and claws, small hairs on its legs and the smallest green body about the size of the letter d on you keyboard, i'm hopeing to see more. last night i could see one in my corals again its very small but this time it was much harder to see because of its position, all i could rearly see was its eyes reflecting in the red light i view the tank with at night, and the occasional pretruding of its translucent claws, other than that i'm gonna post the video's as promised but no time recently:woot:
