Saki is a copper & purple double tail but he looks nearly black hiding back there
So this is my guy's 5 gallon tank. I grew up raising bettas, but I always trusted my mom to know what was best for a pet... so I never knew that bettas needed plants, aeration, gravel and all that when I was younger. Growing up, ours always lived in a 2 gallon tank with those decorative glass beads, and a castle. No aeration, temperature checks, variety in diet, filter, plants, or even water conditioning. Their water was changed completely once in a while instead of only partially once a week. I guess it wasn't as bad as it gets, but it wasn't ideal either.
So mine has gravel with a few decorative glass stones spread out, 2 silk plants, 1 plastic plant, a filter, his castle, and an air stone (that's hiding in the corner behind the green plant) We haven't needed a heater yet since he's in our bedroom, but I keep a thermometer on his tank and it stays between 79-81. I'm not sure we'll even need one in the winter (I'm Pennsylvania) since our faulty heating system keeps this room warmest in the winter whether we like it or not.
Now my husband loves this guy so much he got a betta, and it's in Saki's old 2 gallon tank... since I got this 5 gallon tank, he's decided to get one for his guy too!
