Not all at once,lol, but all of these fish are from neon size to probably dwarf gourami sized and the benifit is no heat required! But as always check your species out on Google to get all the details about the fish before you buy or catch them...I have yet to not find any species that doesn't at least have the adult size listed when researching on Google.
Also, check out
Johna's fish list too, you can order these guys cheap!
