Well I've finally found a source of mysis shrimp
(Thanks littlemsfun )
Went there last night and found thousands, not to mention some more glass shrimps. So my seahorse is very happy about getting live food and is alot more active hunting and not so much sulking!
Sadly not long after I lost my boy the wee girl came down with the same thing, and even with force feeding her (which she absolutely hated), and treating her with furan 2 she went down real fast. But since then the tank has stabilised and everything is fine now, not to mention I finally bought a chiller (thanks organism). Just as well what with the temperatures we have been having....the homemade chiller just didn't have enough guts to keep the temperature down enough....
