do you know where you are going to get the fish from?
How about a 38? I just got one and love it!
36x12x16
Place a wanted ad on craigslist. List the size and dimensions. Let them contact you.
Wow, that's good news!I think a 75 should be safe on most floors. There are tons of options for that size tank
With the 37 you can have some tall Anubias and tall Vals that the Angelfish would love. I would go for the 37.
Good luck!
