Hydroids came back in force though. 3 weeks ago i redosed at 2.8 mg per gallon. i followed up 1 week later with the same dose. all corals look good, palys are closed up and irritated but okay, inverts good as well. 1 0 0. 1. not everything is 'bad'. 2. there is no way to know whether they got into your tank (i'm not even sure its a hydroid)? but yes it looks possible. 3. its hard to tell from your pics were the 'hitchhikers' on the plug or the coral. if on the plug its why some (many?) take the coral off the plug. 4.
In the past month, i’ve been noticing more (what i think is hydroids) cropping up on my rock. can anyone confirm? also, noticed some tiny white specks on my glass, but it was hard to get a good picture. literally look like tiny grains of sand on the glass. no distinguishing features that i. Digitate hydroids, and other hydroids found in reef aquariums, are known to sting corals and fish. they definitely fall into the “bad” category. they are difficult to remove but there are some predators that may consume them. for example the lynx nudibranch and the flameback angel. manual removal and dosing hydrogen peroxide may work also. Sprinkle the shrimp eggs into an inch of water. this will re hydrate the eggs and prepare their shells to be dissolved. add an inch of bleach to the container or jar. be careful not to just pour it in, stirring it into the water over time and letting it dilute. once the shells have all dissolved, filter your eggs into a sieve or net small. What do you mean by fed? things like aminos? is presence of no3 and p04 enough to sustain or increase their population? how much kalk? my tank is only 25 gallons, about 16 gallons of actual water volume.

Hydroids, also known as digitate hydroids, are tiny animals in the same family as jellyfish that can show up in any reef tank and cause chaos. even worse, these pests can often bloom in newer tanks, which can discourage new tank keepers. thankfully, there are solutions to a hydroid problem if you are diligent. But i have definitely seen both species consume hydroids. peppermint shrimp can also eat corals when they run out of hydroids and aiptasia. but shrimp are easily trapped in a trap you make from a half liter water plastic bottle. e) husbandry. for many of us, hydroids only beomce a problem once we start feeding corals.
