Don't get stressed out... Stick with one frog spawn cause once frog spawn starts growing they really take off so stick to one since it is a nano... These guys will find it if they want to... Some clowns take longer to host coral than anemone. But once they get in there they are there to stay
How long does it take for them to grow? Mine only has 2 branch, will it grow another branch in a year or so?, i feed it brine shrimp but my greedy cleaner shrimp takes it off of my coral
Ha ha all living things in tanks are greedy... My three spot damsels Ron the food from my anemone and out of the hands of my hermit.
Hard to say the speed it will grow at... All depends on lighting food quantity and water flow... It grows like wild fire in some tanks and really slowly in others. My advise would be to watch it for about 4 months before you think of adding another one...
Nice inhabitants! If you get other corals, make sure you don't keep them too close to the Frogspawn. They have "sweeper tentacles" which I believe are put out at night (not 100% sure if they are out at other times too). These tentacles can harm other corals.
