And goldfish owners...oh my god. Especially when they're getting feeder goldfish.
"They don't need filters" ...yes they do.
"Good thing they're cheap cause they die quickly" ...cause most people don't care for goldfish properly. A goldfish with proper care, even feeders, can live up to 40 years...
Just wanted to point out that the 1" per gallon "rule" has been proven to be extremely flawed. By that way of thinking, you could put a 12" fish in a 12 gallon tank...which wouldn't be physically possible. In addition, it doesn't take into account fish species that produce large amounts of waste, such as goldfish and livebearers (mollies, platies, swordtails and hippies). Put a 2" goldfish in a 2 gallon tank and the water will be fouled with waste within 12 hours. Also, when stocking a tank, ALWAYS stock for the adult size of the fish, never the size they are currently. Put a fish in a tank it will outgrow and stunting occurs (painful process where the organs of the fish continue growing but the skin doesn't...leads to a rather horrible death for the fish).
That being said, your betraying boys are beautiful, Iseul. I've kept bettas for several years, many in divided tanks. It can work, but depends largely on the bettas' personalities. If they are laid-back and not largely aggressive, it can work beautifully. If you want additional insurance, place tall, full silk (or live aquarium plants) along the dividers on either side to break up lines of sight. Bettas are very visual, so if they can't see a potential "threat" (i.e. Another male), they won't react. Posted via Mobile Device
