Ehehehehe! *nervous laugh* Excuse me while I go put a padlock on my tank...
@ P3- What the fluff?? Kill! Kill! DX
Not really, Betta fish don’t need much space, they tend to get bored and complacent when put in a too large tank.
They are aggressively territorial, and will stake out a small space as their own.
It’s cruel putting a coldwater or other freshwater species of fish in a space this size, because those breeds of fish need space to develop and grow. Betta fish only reach 2 or 3″ in adulthood.
