Fish size

[Chuncan]

If fish size growth is relative to your tank size, what happens if your fish stay in the same tank for about two years, and had stop growing after one. If you move them to a bigger tank, will they start growing again? Or are they done.

Growth is more a product of nutrition and stress (water quality) many people use grow out tank to get them big then transfer them to a bigger tank, most fish slow down in growth after the first 3-6months depending on the specie.

Best bet to grow a huge fish is too put him into the big tank from the beggining, feeding him quality food (pellets, fresh raw fish/shrimp) and keeping the water pristine 24/7, water quality is 50% of the growth spurt, many fish are stunted from the get go cuz of toxic water..

More or less focus on diet and water quality and in no time you will have a great healthy fish!!!

There are many people that would give you that impression.... fish will stay to the size of the tank. Actuall, they won't do that....what they do is "Stunt their own growth"... their gills will start to curve, and they will slow their metabolism down.... this decreases the fishes life span by a TON! And eventually the fish will RIP..

However, as F1 VET mentioned....you can start of with a grow out tank... but ensure to switch the fish to the right sized tank once you see, the grow out tank has done its "growing out" purpose....

Fish growing according to the size of their tank is an old school fallacy. The stunting is the result of nitrite poisoning aka brown blood disease aka methemoglobinemia. As stated above, this condition will drastically reduce the life span of affected fish, decrease their energy levels, increase their chances of contracting diseases, wash out their natural colors, etc. Affected fish moved to larger and better maintained quarters may recover provided they're not in the latter stages of the disease. Keep in mind that this disease reduces the bloods ability to absorb oxygen and transfer O2 to cells and remove waste gases/products. The affected cells cannot repair themselves. And, since fish have self-replicating blood cells (instead of bone marrow to produce new cells as in mammals), the fish will eventually arrive at a point where it will have insufficient healthy blood cells needed to make a full recovery. If the fish can recover, it's likely to continue growing once its red blood count, and immunity system, has been restored.

very good info oddball. Just looked up methemoglobinemia. looks to be the same disease that the blue people aka "Fugates of Kentucky" experience. http://gma.yahoo.com/photos/fugates-kentucky-skin-bluer-lake-louise-photo-200247267--abc-news.html

i've always believed that x amount of gallons isn't necessary for a specific species of fish, but the dimensions of the tank is more important... in a sense, an adequate sized tank with regular water changes can prevent the nitrite poisoning that leads to brown blood disease?
