It's growing around the frag tank at the LFS I go to in Tampa, but since they don't keep it separated, there's no telling where the algae originated. It seems to be growing in small-ish patches, mostly on the egg crate they have the plugs sitting on, or the frag plugs themselves. It seemed to...

Can someone please confirm that this is coraline? I can't find reference to this color being common.

I have a plant taking over and need help with identification. I'm looking for a natural predator. It's in a 75 gallon with a yellow tang and midas blenny - neither will touch it. Sea slug maybe??

Hi Can someone ID this bright green slime alge,mostly on LR.Looks more dusty when I blow off the rock.It looks like cyano but it doesn't go away when lights go off. Thanks

So I've had this for a couple weeks here and there on a few rocks...hasn't gotten any bigger or smaller just wondering which one it is?? Sry about the pics I'm working with an iPhone and it does not like any type of blue light at all!! I'm referring to the purplish red dots...don't mind...

This definitely isn't a creature, it's a growth.. and being that I have positively ID'd NUMEROUS species of pestilent algae, I would def not be surprised to add another. I think my tank is turning into an algae sampler tank. Little bit of everything. This new one is dark purple/black and...

The first pic...I couldn't find this algae anywhere to ID. Its transparent and leafy. The second pic is just a medley of the different algae growing in my tank. There are at least 7 different algae in the second pic. I wouldn't say that I am overrun as of yet. I kinda like the diversity of...

It's about 3/4 inch long, and has double in size in 3 weeks. My trochus snails don't want to eat it. Could it be Chondria?

I noticed in my freshwater tank that I have this weird black algae growing. Can anyone do an algae id for me please?! I have no idea if it's a bad thing or not. What's the best way to get rid of it? I took out all the decorations that had the algae on it, and I scraped it off the intake tube of...

Can anyone ID what this grey-ish colored algae / mold is? If so, what is the best way to get rid of it? Thanks!

It's tiny, about 3mm high, so It took me forever to take a picture of it. I suddenly got worried it's not hair algae as I initially thought, because my snails won't eat it, they meticulously scrub around it. :doh:

Well I tried the search function and archived my threads, and I can't find the link a member or moderator here sent me some months ago. It was an older thread that had a very lg list of nusience algaes, and a thorough description, and control methods on some of them. They were all accompanied...

Anyone able to help beginner figuring out if these two algae are 'good or bad'? They both look nice so I would like to let them stay, but both are growing fast and I'm concerned they may take over the tank and be difficult to remove if they spread too much. Tank is only about 8 months old...

I've been unable to ID this alga. Was told it is a fern algae. found nothing on internet. Any idea what this is. :bigeek:

I have got a lot of dark red algae (I think) growing all over my rocks and some on my sand. I don't think it's cyano bacteria as it's not really slimy and doesn't scrape off very easy. It's more like a velvety coating going by feel. It's a 90 gallon tank and has been running for a couple years...

got this weird algae on a couple of my rocks... i really need to know what it is and how to get rid of it. it started out looking kinda like orange coralline algae, but then formed a brown "coating" almost like a slime over it. it seems like its calcium based because it comes off hard, but has...
