Welcome to AquariumAdvice.com
Most anemones will adapt to reef tempuratures but unless an Atlantic species like a
Condylactis sp., they do not tolerate cooler temps well. A striped anemone sounds like either an LTA (
Macrodactyla doreensis) or a Beaded anemone (
Heteractis aurora) both of which will do best in a 78-80° environment. If your temp is on the lower side slowly increase the temp a degree a day until it's where it should be. Posting a pic if it opens up would help
ID it.
When transfering the anemone from one tank to the other I would hope it was
<<acclimated>> properly via drip method. Sensitive inverts must be slowly conditioned between the varying chemistries of one tank to another.
What kind of lighting do you have over the 29 and how old is the tank? Stable water parameters are very very important when keeping anemones and will not tolerate new tanks well nor will they tolerate less than perfect water parameters. I hope the 29
gal will not be a permanent home for the anemone if an LTA. They get quite large as a rule and will not remain healthy if cramped.
