I saw tiny creatures on my glass today which i thought were the copepods I have been cultivating and adding, but after looking up info they did not look like copepods at all and I believe them to be hydroids. My main concern is: Are these pests that will cause harm? My tank is still under a year old and i hear it can be normal to undergo a hydroid cycle. Will these disappear in time or should i do something about them? All water parameters are in check and the DT is 40 gallons with a 10 gallon sump. Tank inhabitants include: 2 green chromis, scooter blenny, yellow watchman goby, pistol shrimp, feather duster, emerald crab, hermit crabs, narsarius snails, astrea snails, purple and green zoas, kenya tree, pulsing xenia, green star polyps, and mushroom coral. Should I be concerned? Does anything eat these or are they ok to be in the tank? I hear they are pests so im not sure what to do!
