Unfortunately, my six-line isn't playing nicley in my 14g BC sand box with my clowns and needs to go back to the LFS. What is the easieat way to capture him with having to tear down the coral and LR?

what i do is i get a net(mine is 5" accros since i have a 6x bigger tank then you do but should work)
leave it in the tank for a while for the fish to become acustom to it. throw in some food and pull a sneak attack from under. or just take everything out and catch him.

Put some food in a prescription bottle. When he goes in just cover the back with the net.

or just go in with a red flashlight and snatch him at night, that is if he doesnt bury himself, but then its just a matter of finding where he sleeps

hook line and bait ?

It's so hard. You'll almost for sure end up tearing the rocks out. The net idea might work, leaving it in long enough for the fish to get used to it then feeding/attacking.

Or just wait for it to jump out like all six lines do.

Catching a sixline is tough. I ended up chasing him into a rock and then taking out that rock...

A net should work, but you'll just have to be careful/smart about it. If you don't catch him in a few minutes I would lay off for a few hours at least before trying again.

Good luck!

I was wondering where he went at night as i never see him cruising around and don't see him hidden in the LR. I never new the 6-lines buried themselves

this worked for me.

that a 2 liter bottle of coke (if it would fit, if not, get a smaller bottle), cut off the top where it starts tapering (or lower in needed to fit in the tan).

peal off the label.

put it on the sand, and start feeding pellets into the bottle. Once the fish swim in and you reach to grab the bottle, they will not swim up (towards your hand) but rather away. since they can't, you'll have no problem grabbing the bottle with the fish. You might get more than one fish, but that's fine

If it doesn't work today, keep it in there and try tomorrow, don't keep taking it out and putting it back in the tank, let them get used to it.

Yeah, my six-line is a pain to catch. Fast little bugger. Luckily I've only ever have to catch him when I moved. Even with no rocks and 3 inches of water left in the tank he was still a handful...

Great idea. I recall reading something very similar for catching a mantis except they took the cut off bottle top and inverted it into the bottle. Do you think it it owuld be a good idea or even necessary to do that for cathing the 6-line?

Water bottle trap. Use a 16 or 20 oz bottle.
