I bought my first few coral and have them in a small 10 gallon aquarium with a heater and wave maker. It’s been fine for two weeks. Dipped all of them in Coral Rx early on. Tonight I looked at the tank and it’s covered in these small anemone like things. Not sure what that are. I assume they are aiptasia but wanted others to confirm. Could it just be algae? Any thoughts on what to do at this point?
