Speed growing

[xEchOx]

I'm not a chemist so I can't explain scientifically why ammonia is more toxic as the temperature raises, but I do know that it happens. The higher the temp, the more toxic ammonia becomes.

Hmmm... also new to me. Just a thought though... We know that heat increases the mobility of molecules, therefore increasing the rate of gas exchange (which is why warmer water will have less 02) and increasing the metabolism of your fish. Perhaps it also speeds the rate at which nitrifying bacteria utilize ammonia, nitrite, and nitrate, therefore increasing the speed at which nitrate levels are produced. (this is all just rambling) So lets say two 55g tanks have the same exact stocklist, but are set at 77 and 83 degrees. Fish are fed the same, etc., etc. At the end of the week, the warmer tank may have a higher nitrate level than the cooler tank? I don't know. Someone tell me how this works, before I confuse myself some more?

first of all i am not old! but warmer temps are supposed to increase growth.

so i hear

I've been in this hobby for only about 2 years. My father-in-law has had his 55 gallon thats probably older than me and he was the one that got me into this hobby. Evere since discovering all these forums with dedicated aquarist i have learned alot of things , cycling for instance my F-I-L doesnt even know what it was until i told him. Well I feel now like i can teach him a thing or 2 about the hobby. My water is always prestine as I do water changes every sunday faithfully, he on the other hand thinks its too much and he does it every other month BUT can you explain to me how his fish grow an alarming rate waaaaaaaay faster than fish in my tank. I bought him 2 oscars back when I had no idea about keeping fish and I swear that in less than a year he had to give them back to the lfs. Can anyone care to explain that. BTW in his 55 he currently has 5 common pleco's all bout 7 inches, like 5 assorted african cichlids, and 2 more oscars that he bought like 3 weeks ago and there already huge!!! and he tells me he knows more cuz he's been keeping fish for years. WTF!!!!!!!!!!!!!!

Certain fish such as oscars will grow fast even in crappy conditions. I had oscars when I first started and probably only did water changes once a month and they shot up to 8" in no time(way under a year) Everything in your tank except the arow and pbass grow slow. Both of those might be slowing down on growth some because of growth room.

In a similar situation a friend of mine got me into fishkeeping and I now surpass him in knowledge and upkeep schedule. Some people just aren't fully commited.

look at sig

Sorry saw that after the fact. See if that above makes sense.

I started with a 75 which i still have and has 1 jag in it but when i started I was just as bad as he was I had 5 yes, 5 oscars 2 pacu's and 3 convicts and a pike cichlid..check it out just found this pic in my archives its when i first started

I can chime in on oxygen content and take a stab at toxicity. Denser water can hold more oxygen, ergo colder water has a higher potential oxygen content. Warm water being less compact on a molecular level has a lower potential saturation. As for toxicity, a higher rate of metabolism due to an elevated temperature would increase the speed at which a fish processes chemicals. I imagine that also increases the potential harm of some chemicals.

I think that's close, maybe even correct. But I'm no chemist or icyophile(sp?)
