Just out of Curiosity

[Videl]

Just out of curiosity, how big do you think an angel fish will grow in a 10-12 gallon tank. Will a corydoras catfish grow to its full potential in a 10 gallon tank, if not, how much do you think it will grow to. What is the potential size for a pearl gourami and do you think it will grow as big as that potential size in a 12 gallon tank. These questions are just out of curiosity to the extent that i will not put a fish as big as an angel in a tank under 30 gallons.
One more thing:
Is it a myth or a fact that a fish will grow as big as the tank lets. Is it true that a fish will grow to its potential size if you feed it correctly, and that the fish live in a good environment all the time (ie. 0 nitrate, 0 ammonia, correct Ph etc.) to the extent that an angel fish will grow as big as it gets in a 12 gal.

um...i do know that they will get stunted if there in a tank to small and why are you asking this if you are not going to do it

Small tanks WILL stunt growth, and in a very undersized tank, the stunting could be as bad as to cause death. Feeding it properly will help a fish grow bigger, but you probably don't WANT a fish to grow bigger if it's a 12 inch high fish in a 10 gallon.

Fish will grow bigger in a large environment. That, along with a perfect diet, is why fish tend to be much larger in the wild. If you keep a Koi in a 10 gallon, and another in a 5000 gallon pond, the pond koi WILL get bigger, and WILL be much healthier, assuming it is being properly fed and in adaquit conditions.

As for a pearl gourami.... Go look in the fish index, it'll be posted right there. Whatever the size is, if it's more than 5 inches, it will probably be stunted in a tank less than 20 inches long.

I have read that the angels or any other fish that need a large tank will just survive. The whole idea is to have them thrive, not just survive. My bio-lab proffesor told me that they would just live up to their tank size. However I do not know if that is a fact. Just like you said you wouldnt do it, (by keeping it in such a small tank) neither would I.

The cory cats are different. If we are thinking of the same cats, then a 10 gal is perfectly fine. This is where the 1inch per 1gal rule applies. Some cats get to be 2 to 3 inches long, some even longer. I have two peppered and two spotted ones in my 20gal non-planted and they are about 2 inches.

why are you asking this if you are not going to do it

he said the reason is "out of curiosity"
it was actually mentioned twice

forceing fish into a space that's drastically too small inevitably leads to premature death in any fish.

In this case it would also lead to deformaties as the 12" height of a 10g tank would not allow the fins to grow straight, angel fish require tanks at least 18" tall and prefferably 24" or more as they are generally deeper bodied than they are tall.

Obviously, if you keep a fish in the optimum environment - including the right nutrition, it will grow largest, fastest and thrive. Stunting (note - not the deformities that CFC mentioned - that's different) occur in small tanks only if water changes are not done often enough; ie: theoreticaly, if you were to put a goldfish in a bowl and change 100% of its water daily (assuming it survived the stress and fluctuations in ammonia, nitrIte, temperature etc) it would grow to 10" normaly - though it would likely suffer from deformities and would be larger than the tank... On the other hand, if it were kept in the same water (assuming it did not die from bad water quality etc) permanently (even if the tank were relatively large), it would grow for a short period of time and then its growth would slow and it would become 'stunted'. With extreme stunting (as would be the case), it would soon die. Having said that, I don't have any scientific (or photographic) evidence to back this up - it comes from reading a little about wild fish populations and stunting there, and, of course, from the experiences of other fish keepers as well as myself. I thought I'd mention this before someone asks (as seems to always happen when this question comes up).
