my wife just got me a 2 1/2" bgk and im putting a 20 long in our bedroom to grow it out in, what would be suitable non aggressive tankmates? angelfish? silver dollars? anything else?
let him be accustomed to the tank after a week or so,as i have observed they really like very clean water,you can put neons,rummy noses etc... small fishes...but as they grow the BGK may peck the eyes of a smaller fishes.,they love to hide and come out at night till dawn,.BGK is a beautifull fish i have seen a person who owns it for years and its like less than 2 feet it just layed down sideways as if it cannot swim its own weight
they would be juvi sd's and angels, i picked up a couple sengal bichir's for tank mates, still might get a shoal of sd's just because they are always active.
outgrow the tank all it wants, the bgk will get 18" so a 20 long is kind of small for it. just a grow out tank. it just looks really sparse with a single fish in it so i had to add something else.
