Hi, I am looking at purchasing my first fish tank. I just want to make sure that the 30g I'm looking at is big enough for my future stocking plans and that all of the fish species I picked out are compatible. I would like this to be a community tank.
If a 30g is not big enough I would consider buying a 40g. Additionally I would like to know if Caribsea tahitian moon sand, or Caribsea Instant Aquarium Moonlight sand or Sunlight gold sand would be appropriate for substrate.
