Looking for an ID

[nzkiwi80]

I believe I've got pretty bad Dino's so trying my best to ID them. Here's take two on a video, the last one didn't have much movement

I’m Still a novice at identifying these boogers. @ScottB is good at it though!

A little more magnification would help, but looks to be both small cell and large cell amphidinium.

Subject to confirmation from @taricha

I can't confirm either, but @ScottB is right about the most likely IDs.

looks to be both small cell and large cell amphidinium.

That species move like a lost roomba? Does both large and small move the same way?

Small cell faster and can do some spins.

Can it do a barrel roll?

Can it do a barrel roll?

Yep. That's the move I was looking for. (Many other things also do that. But small cell amphidinium can)

So if it's a large and small cell amphidinium - how do you treat it?

Sadly, you picked the wrong dinos to have. Large cell defend themselves and their territory very well. It can take a very long time. They don't tend to leave the substrate and find their way to a UV.

There are a few approaches like the Elegance Coral method, but these can be damaging to coral. Dino-X also carries significant risk. (And I don't like that no one can tell me what the ingredients are.)

The standard treatment protocol is to increase microorganism competition, starting with diatoms. You dose silicates (Sponge Excel) to fire them up. Also, introduce some live mud, sand, rock. The moral of the story is that your system is missing competitors.
