i’m Seeing so many comments like this

will definitely try to go return I hope they let me return it. What would you recommend us to buy instead ? for a startup tank
im not the original responder, but i will say that it is going to be slow going. a couple things that they probably wont tell you....dont add a bunch of fish at once. slowly add them to allow bacteria to stay caught up with doing its job.
at some point, probably in the near future, you are also going to go through an "ugly phase". i guess, be cautious about what you take from the LFS. the ugly phase is a part of the process that generally happens in new tanks, so iif they try getting you to do a bunch of stuff, and buy a bunch of junk to try combating it, dont go for it.
that store seems to just be there for a sale, and not in the business of selling pets, so to speak. all fish and coral are live beings. i personally cant bring myself to kill something intentionally, but they dont seem to have an emotional attachment to it as much as the owner of purchased items would.
if you can return it, great. if not, youre just gonna have to do what you can to push through it. i dont have any personal experience with anemone, myself. however, i know that they are difficult in new tanks. at the very least, you can maybe use the opportunity to try to power through it. i have found that these message boards are a great source, and most times, a better source that some LFS.
what kind of light do you have? someone else might chime in here, that knows more about it, but a quality light will probably benefit.
