Hi, I’ve had 2 kuda seahorses in my tank for about 2-3 months now. They’re alone with many soft corals. I’m not 100% sure of the sex of either of them but I’m assuming the bigger one is the male. The smaller one loves feeding time and rises up to the top of the tank to greet me when I feed her. The bigger one doesn’t do that so I need to find him and give him the food that way but he still eats eagerly. Last night he stopped eating and had no interest whatsoever in the food (mysis). Today, he was very interested and went right up to the food but didn’t even attempt to eat it. He has no lesions or white marks I can see and has always been fully black like the smaller one. Sometimes they change to yellow when they’re courting each other. Parameters are okay from my tests. A:0 Nitrite: 0 Nitrate:10. Thanks!
