i have a 55 gallon tank and these fish look pretty cool to me. the eventual stocking will be: 1 rainbow shark,2 dwarf cichlids,3 swardtails,6-9 zebra danios,and 6-10 black skirts,and of course if its ok the catfish. i read they might eat smaller fish,but full grown black skirts are pretty big and danios are top dwellers. so what do you think,can i get one?
