Are cichlids growth slowed or affected by tank size and environment.

[vanpudin]

I was wondering if cichlids growth rate is slowed depending on tank size and tank environment such as overcrowding. I know the quality of the food makes a difference.
Are africans affected differntly than south american? Just wondering.

Yes, I firmly believe all fish can be affected by tank size, and overcrowding (severe) can affect quality of water and lead to excessive stress and quality of life.

[vanpudin]

Just say if the water quality was'nt a factor affecting the quality of life somewhat, just tank size and population, would the growth rate be slowed?

[rbishop]

They would become stunted.

I believe stress is the key here.

Bad water quality = stress and bad health = stunted fish.

Overcrowding = stress = stunted fish

Not enough food = stress and bad health = stunted fish.

Thanks guys

Hi Guys,
In my experiences with "open drip systems" that move close to 50% water change daily, I have seen fish reach their miximum sizes in 36" long tanks.(oscars for example). By removing the pheromones/hormones, eliminating ammonium/nitrite/nitrate, and reducing DOC's you can grow healthy fish in larger densities in smaller conatiners.

Most Discus hatcheries use drip systems and their bio-loads are huge compared to what could be accomplished by a closed system.(our aquariums).

Just something to think about, Rich

I agree Mr. FM....I should have asked what filtration they had up front...
