Need an ID on this tube

Josh jones · Mar 14, 2016

hello everyone have a very quick question. I have this clear tube and it has double in size in like a month. Nothing never comes out or it never moves lol but here's some pictures and thanks again

My first guess is a vermetid snail (I know it doesn't move. They don't). The tube is unusually clear so I'm not sure but do some googling and see what you think.

I'd probably also recommend arresting that crab in the upper right of the first pic. I can't see his pincers but looks like a gorilla. He'd do fine in your sump but probably don't want him in your DT.

Lol I didn't even seen him I have a few of them that came in on some rock but he is the biggest the others are smaller then a pice of rice lol he hasn't done anything just sits in the rock and runs into a hole if I get close so this is a rare picture but thanks for the info and if it is a gorilla crab why are they bad?

Gorilla crabs will eat coral, other members of your cleanup crew, and will eventually get big enough to catch and eat smaller fish. You definitely don't want them in your DT. General rule of thumb is hairy crabs are bad.

Oh. Also. To catch them you have at least three options:
1. I have good luck pinning them with a chopstick and then pulling them out with tweezers.
2. You can make a crab trap. Cut the top off a soda bottle and invert it so the neck is down inside the body. Tape it together. Put a piece of shrimp inside. Works like a minnow trap.
3. Go in late at night when the tank and room are dark. Use a red flashlight to see what you're doing. You can see red light. They can't.

3, by the way, is also a fun way to see what happens in your tank when the night shift clocks in. It's a totally different place at night.
