My fireplace insert saltwater fish tank is 20 gallons. And I’m pretty happy with having corals and only a
Pinnatus batfish.
What’s your opinions on this.
Edit—If I may ask, what are you looking for in you first fish? . Maybe give us an idea of what you like and we can help narrow the field. when choosing fish a lot of thought needs to go into it. There is tank size, potential tank mates, feeding requirements, skill level, and other things. Better we get a fish you love and have long term success with than one you spend a lot of money on and may lose. Just a thought.
