I'd want however many it takes!
I already have a bajillion (ok, actually more like 14) 1-2.5 gallon betta tanks, two 5 gallons (one with a dwarf puffer and the other will be a pico reef when I get around to it), a 10 gallon divided betta tank, a 10 gallon community, a 10 gallon wild betta community with a pair of
Betta albimarginata and
B. imbellis, a 10 gallon full of albimarginata babies, a 20 gallon betta juvie growout tank, a 29 gallon community, and an 80 gallon with a midas hybrid and oscar.
I'd like to add some more tanks when I have room... I want a 30-ish gallon for a small US-native species tank, a 15 gallon for some licorice gouramis, a 125-ish gallon for a pair of flowerhorns, a 150g for some snakeheads (although they're illegal to own in my country), and a very large (maybe 300 gallon?) tank to upgrade the oscar to so I can also get an arowana, osphronemus gourami, and a few other large species I've been eyeing
