Yeah, I'm not really in to salt water but local fish stores are weird. When I asked my store why they had there java ferns rhizomes planted they told me it was fine and asked where I had heard otherwise and told me not to listen to the internet lol, I dout he even new what a rhizomes is. They also sell semi incompatable fish to people but I think that is mostly because they don't want to argue with customers, Angles and neons, anything with oscars... they will tell them the fish probably wont last long but still sell it to them. They have botia loches in with there african chiclids etc. It's not a bad store actually a pretty good one it's just stuff they do, there isn't and laws or anything in fish keeping so everyone makes up there own way I guess.
Also 3 stores told me that my river tank idea for hillstream loaches was pointless and a circulation fan in there was fine, finally I got one girl (at the good store above) to under stand what unidirectional flow was lol. Also non of them seem to know the sinetific latin names of any fish, I read online that if you want a certain fish (like hillstreams where there are 30-60 some species of small algae eating butterfly looking loaches) to ask for the latin name so you know what you are getting but rarely does the store or supplier even know them.
