Fish Crazy
Are you sure you're not thinking of red tail catfish, OldMan?! Red tailed black sharks get to 'only' six or seven inches; big enough to need some care given to the right tank, for sure, but it's not that big!A red tail shark when full grown will need a tank at least 6 feet long just to hold it, not to really give it enough swimming room. These are fish that should only be sold by special order to people who know what they are getting into and have the room to house an adult. They should never be sold in a typical pet shop to unwitting buyers who have only ever seen fry.
no he is talking about the RTBS: Red Tailed Black Shark. and there is no doubt that a 50g tank is only good for young. size is not all that dictates tank size.
even 7 inch examples are few and far between, 5-6 is most common.
this is not even new knowledge, it was commonly known over 5 years ago, when i started, what's missing here is people with enough experience to know. and sense to listen.
We know he was talking about the red tailed black I've been keeping tropical fish since the late seventies and back then they were common, but the albino ruby shark was much less common than it is today.
