So I am in the process of closing down my smaller old tank and moving everything over to my new larger tank, in my old tank I have a brittle star who came in on some rock and has thrived in my tank, it has grown huge over the last few years and although very secretive it must be about 15-20cms across from arm tip to arm tip, it's a solid black one and has lived with my clowns, banggai cardinal and coral beauty angel without any mishaps, I am not sure I it's worth moving him over to my new tank or taking him to my local LFS, will he be okay with a snowflake eel? Obviously with a snow flake eel CUC is limited is this a good option? What would you do if he was in your tank? Is he likely to turn fish aggressive? He will eat prawn bits and stuff if I see him I feed him a little
