Have only been caring for tropical fishes for forty year's,much less time than ages of some of the fish in the linked article.
Found it odd that no mention of diet's, or temperature's were mentioned, and it is these two factor's, along with proper water parameter's for species being kept, that have proved to me to be most important to longevity.
Perhaps they were mentioned in the article and I missed them.
Many of the more commonly offered fishes such as cory's,tetra's,platy's,swordtail's,barbs,seem to last longer for me and other's? at lower temps with 75 degree's F being much more comfortable for them than temps much above.
Other's such as mollie's,guppie's,Angelfish,cardinal tetra's, and gourami seem to do better longer,in warmer temps.
These are only observation's I have made, and I fully expect to hear from those who keep fishes mentioned in a very wide range of temperatures as well as water parameter's (pH,GH,KH).
Some folk's don't know ,don't research, proper diet's for fishes being kept to see if they are largely herbivore,omnivore's, or carnivores and all fishes are fed same foods.
This result's in poorer health over the long term and fishes slowly begin to deteriorate in health.
Could also be why it is estimated that new hobbyist's stay in the hobby on avearge of one year before they lose interest in caring for fishes that seemingly die after a few week's month's. :silent:
