they are cute little barbs

how big do they grow to, and how many do you have?
i think you should pretend you never got an extension, and that you never built a 16 ft tank, when it happens, as we will all be insanely jealous. you will be inundated with requests for pictures and videos of it too. is the purpose of the extension to have a bigger tank?
maybe one day i shall be able to afford to build a "garage" and then afterwards explain why there are fish in it instead of cars
