Naturally I disagree with this
My scats arnt true scats...silver scats are a trade name because they are so similar looking to an argus fish, they are more correctly known as an austraillian silver butterfish which tops out around 8". They are around 7" and havent grown since I purchased them several years ago. My colombians are about 2" body size...the Puffers might be 2"....and the monos altho they have grown quite a bit in the last 2 months are still a bit larger than quarter body size, and the archers 3.5". You cant really argue that these fish are cramped to death or will be anytime in the extremely near future in a 48*24*20" tank. Most of the fish will be sitting pretty here for life. IMO those sizes are also a tad over stated, granted I do feed my fish about 90% on frozen mysis and bloodworms and their water is pristine so they could quite possibly grow to their maximum size in the wild in my tank. Also monos and puffers, and archers arnt really known for their expecially fast growth rates I estimate I have several years for these fish in this tank. My colombians are a diffrent story tho...they are rather quick growing, which is oK they have a 125G tank in my basement waiting for the day that they need it, I also have a ~450G cattle trough(altho this was purchased for when the Pacu outgrew the 150) and several 55G and 75G tanks....and more than enough equipment to run them...if and when I need to set them back up.
