Freshwater shark question

  • We are currently upgrading MFK. thanks! -neo
There's least 5 true freshwater shark species, all in Glyphis genus and one species that can be found in both freshwater and saltwater would be a bull shark.

^^ This.
 
Those aren't sharks any more than a goldfish or a pleco is. They may be called sharks due to some superficial similarities, like an upright dorsal fin, but they are just common/marketing names so it is hard to answer your question. Bala, rainbow, red-tail black, Colombian, the list goes on. But we are talking about minnows and catfish, not sharks.
 
When considering the six freshwater sharks, it is important to note that absolutely none of them are anything close to being suited for aquaria

Sadly, this statement also applies to a large percentage of the catfish/minnow sharks in the hobby as well.
