Dino ID and is this cyano?

[FLReef32043]

I have got caught up with work and have NOT been cleaning up my wife's tank as well as I should (nor mine for that matter).

I was treating my tank (75g with sump) for dinos by dosing silica to try to eliminate Procentum dinos. I had THOUGHT I was winning and sure enough soon as I thought it they came back like gang busters.

Then my wife's tank started showing signs, but also I started seeing some "black" matty stuff. Since the dinos mat in my tank I though perhaps this is the same thing. Now I'm not so sure as it is pretty nasty black. Also have some GHA problems going on. This tank has two clownfish, a goby/pistol shrimp pair and a fire shrimp as the only occupants (and a whole lot of cerith, dwarf cerith and some nerite snails.

Before I start to figure out a solution I'd like to compare my thoughts about cyano with you all, Also if anyone can confirm which TYPE of dinos I have. @taricha?


These do NOT seem to have the hooked beak and they seem to me to be more of the described "sesame seed shape." Add to that my sand bed does not seem to be as impacted as it is in my larger tank.

Also note that about the 0:44 second mark going till about 1:10 there is a "something" in that video. If this were from a freshwater pond I'd say it was a larval cyclops but far as I know they don't have that in saltwater and I have no idea how it would have gotten in there anyway. Any ideas?

So the black stuff is cyano.

congrats. these are not a dino. this is a cryptomonas or rhodomonas.
this is what they look like in my system.


your hunch about the something in the video between 0:44 and a minute is correct - this is a nauplius (larva) of a copepod

I may be wrong but they looked a lot like dinos to me... maybe Amphidinium sp.

And cyanos too, Oscillatoria sp. probably.

Well that is comforting news

I did clean the tanks (both my wife and mine) and the majority of what I got off the sandbed and rocks did indeed come off in mats. 24 hours later it had not returned in volume - which it did when I had the bad dino problem. It did come back but nowhere near as bad.

So water changed today for both tanks and I have a couple more power heads coming for the wifes tank to try to improve flow. Also working to adjust the flow in my 75g tank to try to alleviate some of the conditions for cyano.

We'll see how this goes.
