resulting in the stunting of the fish. I am a strong believer in having fish in an adequate home, based on their expected adult size, from the beginning to avoid an issue like this altogether. Of course upgrading as a fish grows works also but you have to be careful to say on top of your water conditions and increase tank size as needed.
Ahhh, makes sense. I also believe fish need to be kept in an adequate home to keep them in tip top shape and give them space to grow. I feel that they should be given respect to the point they are given a tank larger enough to provide edaquate swimming room too. How awful it must be to be a large fish crammed in a small "container".
Thank you for explaining what really causes stunting. I will have to pass this info on to my mom so maybe she'll leave me alone about adding bala sharks to my tanks. I told her awhile back what size tank they need and she won't listen because "in her experience" with a single specimen, "it worked". I never have agreed with her...poor thing must have been so depressed.
