6-Line causing trouble with new mates

[yeldarbj]

I added 3 new fish yesterday - Carpenter's Wrasse, Blackcap Basslet, and a small Yellow Watchman Goby to a 65 gallon tank with about 100 lbs of rock. I have a small 6-line wrasse that does not appreciate its new tank mates, especially the basslet. I knew I might have trouble with the Carpenter's Wrasse, but so far there is just a little aggresion toward it. All three are about the same size, approx. 1.5-2 inches. The 6-line pays zero attention to the small watchman goby.

How long do I give the 6-line to adjust to the new inhabitants before yanking him out of the tank? I thought the blackcap basslet would do a better job of holding his own.

I'm going to try to move some of the rocks around today to see if that helps. Any other suggestions?

I added a Sailfin Blenny a few months back, and my 6 line harrased it for about 4-5 days and has not bothered it since. Give it a few days.

I'm hoping the blackcap will make it that long. He already has a few scuffed fins. The blackcap has been hiding in a corner of the tank under a powerhead and behind some rocks.

6-lines can cause a lot of trouble in small tanks, espcially to similar sized and shaped fishes. Sometimes it improves after a little while, but sometimes the only solution is removing the 6-line.

6-lines are the devil... I would get rid of it if you ever plan to add more fish.. he will not tolerate and probably kill any new tankmate... The blackcap prob wont last to long... Replace it with a cryptin 6-line. they are so much cooler!

The 6-line has been removed...everyone is happy...and peace reigns in the tank.
