Right, I've just got back from Burnley after visiting a petshop which had a nice collection of tanks & fish (and a Macaw living in the shop saying Hello to everyone!!!), and I spotted something interesting....
It measured 24"x10"x10", and was just a smidge under £17 (about $30), and I instantly thought RIVER TANK!!!!!
My wallet started screaming at this point, so I had to leave it in the shop for now...
So, I got thinking, how would one simulate a river or stream flow?
My thoughts were a pump/filter at one end and the inlet at the other (so the water flows only in one direction for the fish). But what sort of pump would I need?
Next of course is to have a nice even flow, so a spray bar would be good. Then there's tubing, that'll be hidden under the gravel/substrate.
Next, what would a Hillstream loach be OK with as a subtrate in flowing water? Then there's decoration (I'll probably just simulate my local river), maybe cleaned up river stones & pebbles?
oooooh!!! I can't wait to get the tank and build it all up!!!
Added a quick sketch of what my mind's come up with...
