I've spent at least $1,000 on my five tanks. The live plants in one of them cost me $100, and I've got $50 substrate in one that is made by ADA. The tanks themselves range from $150 - $250 in price. Then there's my empty
three foot tank that cost me $1,000 on top of that which I still have yet to divide so I'm estimating sinking another $500 or so in setting that up with a canister filter and live plants.
My imported Crowntail pair cost $100 so they better be the longest living fish ever, but the rest are just overpriced pet store mutts that I've collected along the way.
Luckily I work full-time and I don't drive or go out much so I have $20,000 saved up in a high interest account. If I didn't, I probably wouldn't have so many fish, and only females since they aren't as delicate with things like filters and driftwood.
