Anyone know how fast these fish grow? I know they don't grow to large, but I'm just curious as I plan to keep an ery with it once it gets some size. Right now it's maybe 2-2.5". I figure by the time it's 4" I can add an ery, hopefully it'll be girthy by then. Also, mine has like the block spotting, not the actual jaguar pattern, I don't see larger ones like this so do their pattern change as they mature maybe? Just something I noticed and was curious about.
