Lol sorry I have no idea what kind of fish these are either! I've seen several types but can't remember the names. Is there any that don't grow too big that get on with smaller fish?
 
bala sharks or silver sharks (same species) and there are red tailed black sharks, both need a 75 gallon bare minimum, and the balas like to be in small groups
 
Iridescent sharks grow to 3 ft and I wouldn't recommend housing them in anything other than a public aquarium.
They say that they only grow to 12 inches in the aquarium, but I'm fairly sure that has negative effects on the fish.

Also, there are no true aquarium freshwater sharks. They are only called sharks because they look like them.

Ahh, a problem there! there are no "small" sharks in the hobby, unless you consider 7-8 inches small.

the Red Tailed Black Shark, is about the smallest at between 5-8 inches. it also needs lots of water, usually stated as, 50 ukg+.

the Rainbow/Red Fin Shark, can get up to 9 inches, and has similar tank requirements to the RTBS.

the Black Shark, can grow to 30+ inches and will need 100ukg+

the Bala/Silver Shark, get to 12 or so inches, and again need 100ukg+. they should also be kept in shoals, which takes the water volume up even more.

the Columbian Shark/White tip, Silver Tip, grow to around 14 inches. again needing a tank of about 100ukg. it should also be kept in groups. it is also Brackish when mature, and really suffers if it does not have it.

the Iridescent Shark/Pangasius Catfish, Shark Catfish, can reach over 40 inches. and needs, about 150ukg.

this is not a definitive list, I'm sure i missed some, but it is representative of the "shark" stock out there.
 
Given the above, then I guess 7-9" is small...
That said are most of those really "aquarium" fish? Do people really have aquariums at home to keep fish that size?
Shame really because hubby and I both wanted an albino rainbow shark, but I just don't think it's going to be small enough to keep in our current aquarium. How fast do these creatures grow?

I fully agree, it seems unlikely that many of us would have tank big enough for these fish. this not only affects the "sharks" we keep, but is far from unusual in the hobby as a whole. for me, if i am honest, its one of the biggest problems the hobby has.

as for how fast they grow? well my RTBS reached 6 inches in under two years, though i think it has stopped now, as it is developing white tips to its fins. i think the Rainbow is a little slower growing, but would need confirmation for someone with more experiance of them. I think Columbian and Iridescent sharks grow much quicker, and have the added problem of an extreamly large mouth. this makes them a problem to all smaller fish.
 
Well most all sharks grow big. The smallest shrak needs a 75 gal tank, and they grow up to 10 inch.
 
oh no these were little thin silver things just like a minature shark, dont know if they were minnows then or what but they look convincing to me :)

they sound like Silver/bala or, more likely, Colombian/ iridescent. all get to 12 inches at least.

paul_219 both RTBS and Rainbow will not reach 10 inches, indeed the RTBS will be lucky to reach 6.
 
yeah they were silver/bala sharks, guarantee it!

cute as anything as 1" babies aren't they! ;)
