hey i’m upgrading to a new tank from 55gal to 120 and im interested in propagating some zoos maybe to sell and trade. I was wondering if anybody with alittle more experience could offer some advice on the types of rock or whatever i could grow them on that would b easy to break off or can you cutt them off at the "stem"? Also does anyone have any advice on some other coral that are easy to propagate? And how easy are Acan corals to propagate? any advice will be greatly appriciated! thanks!

i recently started to grow phyto for my 55gal reef tank and was thinking about growing rotifers or copepods. Does anyone have any suggestions whether i should grow rotifers or copepods; and depending on which ones i grow can i feed them the phyto im growing or should i buy food for them?

Alrighty then i have been looking around at some food cultures and setting up a food chain to try and set up a ten gallon food tank to produce a portion of my food. The species im looking at keeping are as follows,
Carnivorous foods
Brine shrimp
Copepods
amphipods
herbivorous foods
Gracilaria
Ulva
a few questions should i make this a seperate tank or have it like a fuge?
And Is there any larger specimens i could house?

My p. shrimp was loaded down with eggs so I put her in my refugium tank and turned the lights off each night. Last night she molted. In the molted shell there is something that looks like a egg sac, in the same place where she was carrying the eggs. I have seen a molted shell before but never with something like this. Does anyone know what this is that she left in the shell. She does not have any eggs on her now so I put her back in the main tank .

I have two Helfrichi Firefish and I noticed they sleep together in the same burrow. Is this proof they are a pair?

Can someone please tell me how to care for this item, what do they eat? where should it be placed? i’ve noticed recently that the yellow heads are always hiding and doesn’t seem to be coming out lately.
