Growing on my Glass

[AJ_77]

"It is of course very difficult to offer a reliable ID based on the scant description here, but in your case I would guess that the stationary "snowflake-like" animal is a type of hydrozoan jellyfish that have branched tentacles and actually have a small sucker on one branch of the tentacle with which to attach to the wall of the aquarium. They are capable of asexual reproduction under ideal conditions in an aquarium, and can become quite abundant for some time, but usually disappear on their own about as quickly as they appeared in the first place."

<font size="2" face="Verdana, Helvetica, sans-serif">Rob: Thanks for the great info and link. These are exactly what I have right now, in abundance. It seems the Astraea snails may be mowing a few down as they go over the glass - any concerns with such an addition to their diet?

Cheers,

Flatworms. Hmmm. I think I have these guys in my new 75g tank. They're quite small, <1mm, whitish, and basically hang around on the glass, particularly in spots where the algae is not getting cleaned off on a regular basis.

What risks are there leaving them be? Are they more of a visual nuisance or is there risk of them wiping out other forms of small critters ie., if they are predators of copepods.

Will a 6-line wrasse help keep them in control?

I was going to guess the "sled" things are flatworms too. Until I read the original poster said the things were clear color...
Anyway, if they are indeed flatworms, I feel for the newbie. Doesn't even know what hits him.

Thanks Rob, I was having problems finding that pic of the Hydrozoan Jellyfish ;) . I would also like to mention that there was a large population in my sump, without any light in there at all. After a few months they just disappeared, as if they were never there... so don't worry about them, just go find a magnifying glass :D .

P.S. Welcome to the wonderfull world of flatworms. HE He he I givin up trying to irradicate them. My new approach is something like this, when your cold you say to yourelf "I'm sitting on the beach in Hawaii suntanning", well "I love my Flatworms, they are so beautiful"... I think it's starting to work [img]tongue.gif[/img] :rolleyes: [img]tongue.gif[/img] LOL

Sorry D, I didn't see your post. The Flatworms are just a visual nuisance , I think they are actually good little critters, it's just there are 2 darn many. Don't bother going out and buying a bunch of fish, maybe a 6-line Wrasse but it seems that these are a hit and miss kind of thing ( I think i'll buy 1 on the weekend ). Everytime they accumulate just get the old airline tubing out and syphon out as many you can get. When there numbers are low they don't bother me at all... I think :confused: LOL
