weirdd thing?

ohkayy.. so I have a 30g in my room with nothing in it but some rocks some plants and a light overhead.... anyway i had it sitting there almost as a little experiment... trying to see if algae would grow. but about 5 minutes ago i seen a little bug like thing and it looked like a cross between a scorpion and a centipede swimming in the water... i noticed two of these....any ideas what it could be?

The larvae of some bug. Algae spores are in the air, and with enough light they will grow in about any water that is not toxic. Now you have me thinking about those bad 1950s monster movies that have little bugs turn into big, dangerous things. One other possible explanation for the weird creature is something from the lake.

the next godzilla perhaps?

Well, maybe at least the next Bugzilla

It's that time of the year... Reckon it could be mosquito larvae?

well maybe but i done know its like maybe 3/4 inch long and it looks just like a centipede and it swims really fast then just sticks to the side or something. you can only see it when it swims i guess it hides in the floating plants...could this be bad?

What ever it is, the bug larvae may not be so good for the aquarium. I would smush it or try to catch it, then put a glass hood over the aquarium to keep other Bugzillas from depositing their eggs there.

Does the larvae look anything like this?

or this?

it looks like the first one
what is it?

Isn't that a mosquito in the pupal stage?

Nope, it is actually a larval dragonfly. It is an aquatic predator at that stage and then an airborn predator after that.

That pretty well rules me out as an entomologist.

LOL, I'm not much of one either. I only know about them because I used to see them in the ditches and in the cattle troughs on our dairy in Oregon.

so its gonna turn into a dragonfly??
i wanna pet dragonfly...

Somewhere I read that dragonfly larvae will attack and eat small fish. By small, i mean adult guppy. A dragonfly exhibit would make for quite an interesting aquarium. You could probably feed them raw hamburger. If you drain half the water out of the aquarium and put in some big rocks, you could have a dragonfly aerodrome and hatchery combined with a burger stand.

indeed... how long will it take for a larvae to turn into a dragonfly?

and can they swim?

Only the larvae can swim. The adults would need the aerodrome. Mr. Google probably has information about their life cycle.

okay...do they need like male and female to breed or will they pull some crazy dragonfly breeding outbreak in my bedroom?

My guess is you would wind up with an infestation of the things.

Yes they need male and female to breed. They like to catch bugs in flight so if you can provide the adult with some live food you might just have something. I have noticed they spend their lives around bodies of water and will land on just about any surface. Make sure it gets plenty of places to land and good luck. By the way, is there anything in the water right now for it to eat? I imagine it would eat mosquito larvae or other water bugs.

well theres some live plants floating around and some algae...also i put goldfish pellets in there and there at the bottom with like a moldy puffy dome around them. its a 30g would that be big enough for a aerodome?

That's kind of a problem. The adults need lots more space to fly in. Raising them in captivity doesn't seem very practical, although watching the larvae develop may be. The white stuff around the fish pellets is probably mold; you need to syphon it out. Dragonflies like to hang around lakes, so an outdoor pond would work better than an aquarium.
