got 2 new o's--and they are really shy right now--hide behind rock all day-wont eat,etc. how can I get them to interact more--get them use to their enviroment ?

Give them time... It could take a week before they adjust... They will come around!

mine are doing the same i got them 2 days ago, they come out when i am not close to the tank i just leave a couple of floating pellets in for awhile and they will come out and eat it, but i am going to get some blood worms today to try and entice them...

Give them time and they will soon be buzzing around the tank begging for food

im just hoping you have your issue worked out from the previous pair. i would hate to see a repeat.
