Corals dieing off one by one
I have had a tank for 15 years. Some of my inhabitants are over ten years old!!! My corals are all doing great except for lately, frog spawns are losing pods one by one. And how i mean that is, The coral in its whole is doing wonderful. Growing fast and looking how they should. The frog spawns grow so fast that i keep fragging them and putting them in multiple spots. But, head by head, they seem to be dieing off. Its wierd. I have one normal frog spawn, and two green ones. They were split about 8 months ago. In the last two weeks, the heads on only 1 green and one brown are dieing off. The other green one is doing better than even. Its not water parameters in my mind. I feel something is attacking them. Now it looks like something got the hammer coral. This is a 5 years old large hammer. It has done well the whole way thru. never one problem with it. it seems like something got it last night or threw out today. Hard to tell. ive been working long days. all other softies are fine. I worried something has taken a liking to the corals and is feasting. I have not introduced anything in the last 6 to 8 months. I have a blue tang, yellow tang, foxface, strawberry dotti back. bengii cardinal, green chromis, tomato clowns, mandarin goby, watchmen goby. australian red leg hermit crabs. some fire shrimp. urchins.
I would think that if it was a disease it would affect all softies, or at least all the heads on the frogs. One by one seems a little suspicious. Any thoughts?
