Growing speed for silvers

[TLair]

No mate.. they'd easily do 10"+ in the first year.. i got myself a couple of aros around 5" this jan and they are easily 13"+ but not more than 15".. aros are not like oscars.. they(well mine) eat only when they are hungry.. look at the stomach.. for a small aro, 2 to 3 times a day is great.. 12"+ aros 2 times a day.. 20"+ people generally say feed every other day.. i got a 22".. i still feed twice a day.. but back to the question.. dont dump too much food in there.. observe for about a week and feed only what is required.. cheers..

All right thanks! I am actually about to go check on my guy and see how his night went, he is probably stuffed, he had about a third of a market shrimp yesterday

UPDATE: after checking on him just now I noticed that he still hasn't swallowed the piece of shrimp, even though it was smaller than the first one i gave him. It does look like the size has gone down but it is still in his mouth. He also looks very stressed, and is swimming very slowly around the tank and swimming lower than he normally does. Finally, he is keeping his fins in more than normal and his dorsal is down. Any advice?
