Betta Fish: This is House

House is my opal betta i’ve had for about a month now, i always check on the tanks before bed but tonight i couldn’t find him. i feared the worst that he had jumped out and gotten himself killed, after checking EVERYWHERE i decided to sit in front of his tank and watch for him. so i turn the light on and wait… a few minutes later i see a flash of white in the small cave system within the tank, turns out he sleeps in there! i had no idea that he could even fit!
