i have a spare tank i can move the neons to for now... and wait until the 10g gets here tomorrow. the only problem is i don know what to decorate the 10g with.Look for free or very cheap 10g tanks...but return your neons ASAP. Your current "tank" is really just not big enough for even your betta...I don't believe it's even a 3g. You can & should do better for him alone...Step up your game!! Don't try to justify keeping him in a "lesser" tank. you can & should do better...
