I have a lot of tropical fish books. Most notable fish authors such as Dr. Herbert Axelrod who is the founder of Tropical Fish Hobbiest magazine and many of his books he wrote stated that fishes usually grow smaller in an aquarium than in the wild. For the record this is early work, well out of ...

Also I go to a piranha messege board frequently. Most of the people over there would want a 15+ inch Black Piranha. They can get to 24 inches in the wild. People can usually buy the Black Piranha when small and they know that the chances are slim that the Black Piranha would grow to 15+ inches in an ...

Most fishes regardless of what they are grow smaller in an aquarium than in the wild. How do you know this? Of all the fish I can think of that I have collected in the wild I have seen them larger in captivity. The point I think is that if they DONT get larger in captivity then we are doing ...

fish DO NOT grow to the size of the tank, this is an utterly stupid misconception. they only get STUNTED, which is not humane and shortens their life span. if you want to keep pangasius sp. in captivity, buy a public aquarium. preferably one on the large side. anything else is the equivilent of ...

Here is another owner. He said this about his Iridecent: "I have 5 Irridescent Sharks. I did not know they would get so big. One is 16 years old and 45 cm long. The other 4 are at least 5+ years old, 3 are 45 cm long, and the small one is about 15 cm long. They were all about 7 cm long when we first ...

I do not think fishes grow bigger in an aquarium than in the wild. Fishes can eat more stuff in the wild. Here is a person who wrote that her Iridecent grew from 8cm to only 33 cm. She had it for 11 years. Keeping a fish alive for 11 years, she is doing something right. Here is her post about her ...

Maybe these will give you an idea: http://www.planetcatfish.com/images/full/pangasiidae/pangasianodon/hypophthalmus/9.jpg http://www.planetcatfish.com/images/full/pangasiidae/pangasianodon/hypophthalmus/8.jpg I think that you have a problem on your hands. ;-) :roll: They grow that size in the wild ...

I have four of them. They are about 4 inches now. How big will they get? Anyway, someone told me that they will only get about 11 inches in an aquarium. That person has theirs for about 8 years.

I have four Iridecent Sharks. They eat anything, like flakes and shrimp pellets.

I need some other fishes in the tank. My tank is getting quite boring. Which fishes did you have with your Asian Redtail?

I did not return them. I know the catfishes will get big if I feed them. I like big fishes such as Pacus. I kept Pacus before then I returned them to the store when they got too big.

I just set up one of my fish tanks. I used Bio-Spira to cycle the tank. I read around the Internet that it suppose to cycle a tank within a few days or within hours. I did some research and the people in the message boards said it works, the Bio-Spira. I do not know why mine did not work. My ammonia ...

I just got them. At the store, they were all peaeful together. They are 3 to 5 inches in length. Will they be aggressive to one another or will they live in peace as what I saw in the store.
