Some of them are 3 and half, big one is almost 5 years. Current tank is 55 gal (to give idea of their size). I suppose they are stunted, they used to be in a 20 gal (not of my own doing), what should I expect on terms of life expectancy or growth? Thanks in advance for any advice.7yr ⋅ ptyblog ⋅ r/Goldfish
