I looked locally, petsmart sells 30's but there rediculously priced. And my best bet fish store moved further away from my home. Which ticked me off I really loved there services! (PetSmart 30 Gallon 195.99) My project is a Mudskipper habitat. I was thinking maybe use the current 30 gallon and upgrade to a new 30 gallon but my 30 gallon is a 29 tall.
