I just got my very first tank:)
I was recently given a 5 sided corner aquarium, being unsure about the size I went to petsmartwith the measurements unfortunately they where no help at all so I measured the water, it fit 45 gallons, so with the 50 pounds of gravel I assume about 50 gallons. I added the chemical on Sunday. I was planning on getting fish tomorrow night and was hoping for suggestions, I have a 20 month old and a 6 month old so something colorful and exciting would be great. Thank you all for the help.
