I saw the fish below at the fish store but I couldn’t tell which type are they, does anyone know what are they and how many gallons they require?
Also a sign of stress, they could always be new in or something. There's also a (Imo) a horrible colour strain called "metallic" or something, which look like they have washed out colours. I don't know why anyone would want that.I’m curious, what pet store were they at? Their color looks super dull which generally means that they are unhealthy.
