Stunted growth in fish
I've heard that over stocking an aquarium can lead to stunted growth in fish. Is this permanent, or will the fish continue to grow when the tank population has diminished? Is the effect the same on all freshwater aquarium dwellers or does it change between fish (tetras and plecos specifcally) , snails and shrimp?
Any advice would be much appreciated!
Just speculating here but I think that stunted growth has more to do with tank size than stocking levels... although too small a tank can easily be overstocked with fewer fish so one can lead to the other.
I think that if you use the minimum tank recommendations in the profiles here there would unlikely be any cases where a fish might end up stunted.
It applies to all fish, and it cannot be reversed. The fish so affected will have a shorter than normal lifespan, and along the way be subject to other issues that a healthy fish would be able to fight off. One of these is usually the cause of death.
I know nothing of how this affects, or if it does, invertebrates like snails and shrimp.
You might find some more info in my article on stress, here:
Thanks Byron, that was a great read!
is it true the size of the fish will be stunted but the insides of the fish will continue to grow cause it to have a poor life span?
On the tank size and water, we know this is a critical relationship because discus fish breeders can raise many more fry in smaller tanks solely by doing 100% water changes 2 or 3 times every day. If these are not done, the fry will not develop properly due to the water conditions which are caused by too many fish in so small a space.
Thank you Byron! This is a great website. I am fairly new to the fish keeping world and this forum is the best that I have found in my extensive searches. I can't wait for the day that I am half as experienced and knowledgable as most of the people who frequent this site! My fish also thank you, without the advice I've gained I'm sure that I wouldn't have nearly as happy and healthy fish as I do.
