If the study of saltwater fish is marine biology what is the study of freshwater fish?
what is the study of fresh water african cichlids?

Mohamad R asked:


This might seem a little far fetched but i was wondering whether the black bream that i catch at the river can go into a fresh water aquarium that i have at home, i have read somewhere that saltwater fish can be converted into freshwater. If so, how do i go about doing this and how do i maintain them.

Matthew L asked:


I was told that aquarium owners convert small freshwater fish to saltwater. I tried searching for it, but only gives me aquariums not fish. I’d appreciate any help.

ThaDude asked:


and how long would a freshwater fish live in saltwater before dying?

shannonshambles asked:


What I’m trying to say is, is there a visible difference between the two. Do saltwater fish have different fins for navigating in different currents or something like that?

The reason being, on my homework there’s a picture of a fish and I’m supposed to determine what environment it lives in.

Dustin A asked:


Could you explain the difference between brackish, freshwater, saltwater and pond fish.

LuvShabby asked:


I picked up some sea shells from the ocean and I want to put them in my freshwater fish tank. Why can’t I and is there anything I can do to clean them so I am able to put them in?
