They are new, like within a week new. I had moved them twice sense I first got them, once to a 10 gallon tank, from the 29 gallon tank and then back to the 29 once I got it setup. They are both active, but sometimes kind of hide. They have had the stress stripes sense the minute I picked them up to view them at Petco. My question is How long will it take or does it take for them to go away? I don't plan on moving them anymore for a good bit now, but may be adding new room mates for them, still undecided on that though.
