Youd need more like 100k min to give it a good shot.
Lab test fee's are high
Permit costs are stupid
Power bills
Water
Pumps/filter
Tanks
Lots of food
$$ for stock(say 1k + shipping for a good aro)
Remember you need more than just money for setup costs, you may not sell fish and they may sit around for a long period of time. There is all ways unforeseen costs(acc, business reg and the such)
How many 2k+ aro's can nz buy?
Iv looked long and hard at importing fish, better money else where in the industry.
Not trying to knock you are anything. Find a niche and nail it, thats what im doing.
