The pic below is of two tin foil barbs that came with a 55g tank I bought. The tank was never cleaned, water was never changed, Water was only added for evaporation. According to the seller she had these tinfoils for 6 years.
Unfortunately they both died within 4 hours of being acclimated to clean aquarium water.
