blue rock looking thing in my tank

[FishmasteR2002]

it's the second time. I know it's not a rock. The only fish that could have ''laid'' this thing are my 3'' Covict, 3.25'' Firemouth, 3.5'' Flying Fox or my 4'' White-tailed Black Shark. Any ideas?? TIA

Clueless.

my guess will be the blue crayfish molted.. but i suppose you'll say the blue cray is in another tank?

[FishmasteR2002]

.Yes the blue cray is in another tank. I'm just going to leave it alone this time and see if it is anything. Thanks for the replies.

Size? Shape? Composition?

I can't think of anything that would come up blue. Otherwise, there are several native fish species that actually have these rock type things form in the stomach, as a result of the foods they eat (chiton, bones--indigestable stuff). These stones are occassionally vomited up. They have a specific name, I can not think of it right now. It may be something similar, if you can identify the source of the color in something you feed regularly that would be calcareous or chitonous.

otoliths? No, that has to do with the inner ear...

any way you can snap a pic for us?

I hope it's not that stuff that falls out of the back of airliners, because we all know what THAT is!!

clueless, too

[wetmanNY]

You mean the stuff that tastes like Vick's Vapo-Rub? I heard it's great for clearing yellow discoloration in aquarium water, if you can get it in the tank before it defrosts. Also it keeps your beer cool in the Igloo. Watch out that it doesn't stain the silicone on your aquarium. That's the only reason I can think of not to use Airplane Blue Stuff that Falls from the Sky.

I think I'll stick with conventional ice for my beer, thank you. Yuk!

Did you read about the guy at STL Intl Airport who flushed his ferret down the airlane's toidy? Imagine that chunk landing in your yard. (And yes, the guy is up against criminal charges - he broke its neck first and killed it because authorities were going to confiscate it). It's a sick world. :(

Um, how do you know it TASTES like Vick's Vapo-Rub? The warning label says not to put it in your notrils, much less your mouth!! Personally, my weird cravings are for Elmer's glue and Play-doh; must be a salt deficiency:eek:

[wetmanNY]

mmm...Play.. D'oh! ..too salty!

[FishmasteR2002]

I will try to take a snap of it today. Is it possible for the chlorine(chloromine) to solidify into a rock? Well hopefully after you see the pic you can help me out. That guy that flushed the ferret at 30,000 shouldn't face criminal charges. They should flush him from the space shuttle while its in orbit. How mean must a person be to flush a ferret??? Some people.... Thanks again for the replies. :)

since chlorine escapes from the water as its ventelated (if you don't use dechlor) then i'd say its pretty impossible for it to build up too high.

[Faramir]

Yep. Enough gaseous chlorine to make a visible solid rock would kill everything in there.

Besides, how cold does chlorine have to get to solidify?

[FishmasteR2002]

It's gone.... I came home last night and it was gone. This is the weirdest thing that has ever happened to me since I started to keep fish. If it comes back(whatever it is) I'll snap a picture of it. Thanks anyway. :)

we had a few 'blue rocks' in our tank as well, turns out they were the little rocks that are inside the filter media in our HOB filter. activated carbon i guess? hope that helps.
