It was the Dotty in the DT!

[Ripperj]

When I first added a dotty back and a 6 line wrasse to my DT, I was unsure if the 6 line had fin rot or was being nipped. After nursing the 6 back to health for 4 weeks in a nano, I tried adding him back to the DT, within minutes the dotty had torn big chunks of the 6 lines tail. MAjor bummer, I was going to take the nano to work and make it shrimp only. I put the wrasse back in the nano, but probably should have put the dotty in there instead.
And they say 6 lines are bullies

So are dottybacks. Two aggressive fish, one will win.

Dottybacks are nasty fish, my friend has a purple one w/ a female clown. There is no longer a male because they ate him. My friend & her husband came down to find the dotty & the clown looking like a couple of fat kids in clothes two sizes too small. They never would've bought the dotty but she came w/ the tank from someone getting out of the hobby.

When you say dotty back are you talking about the Neon?
