My best friends taking Phantom, my black DT and she's planning on buying a 5G. I told her to make an account on here and ask questions because I don't know much about filters and what you can put in with bettas. She's either going to divide the tank and put a female on the other side or get something else. I don't think she's had a fish before, at least not one for long.

I'm going to be going to Petsmart or Petco with her to buy the essentials. I've seen posts about ghost shrimp. If she got a 5G could she have a ghost shrimp or what else could she have? I have no clue so any help would be greatly appreciated! Thanks!
