Hmmm but they are not very particular about water parameter... LOL... SO other than the nutrient level, bascially is the feeding that cause them to be difficult..
OMG, How dumb can I get!!! I might have found the problem why, I kept feeding but sun coral still receded.. Becos I squirted them with food mixed in Freshwater instead of tank water... It might be the problem...
You will need a "fishbowl" or kreisel tank... Do a search..
Food will be rotifer and seperate from main tank...
Seahorse fries are free swimming and they dun hitch until later stage...
