Ok, so i have a 55 gallon that is packed to the gills full of fish, and I am thinking of upgrading. My dilemma is that the next biggest tank that will fit onto my stand is a 75 gallon. Do you all think it is worth upgrading to a 7, or should i jump for a 90 gallon that will take some modification of my stand.
I am a carpenter so i can probably make it swing, but it will probably end up doubleing the cost for the 90 upgrade vs the 75. Just planning for when i get that job good ol' obama keeps talking about creating or saving
Second question, I would really like a stingray, do I need to splurge on a sand substrate? I have heard gravel is rough on them... and any other things i need to know about them?
