Wow

That's a bit bigger than I expected! On the upside....I get to buy a MASSIVE tank
I really want a 150 gallon within the next 3 years, and since I only have Charger and Prowler, that will leave 50 gallons for a new addition
I'm already planning to dig myself a pond, but that all depends on if I move to Cornwall when my parents do in a few years. I can't have a pond here because my garden is on a slope and it would be a nightmare to dig, plus I don't trust my neighbour's dog

Ideally, I'd like a 1500 gallon pond, but that's big money...
Thanks for the info guys, but just one more question before I fall asleep on the keyboard... How long have I got until my guys stop growing? If it's possible to put a time on it...
Charger is about 6 months old, and Prowler is probably 20 months by now. I won't be able to upgrade to the 150 gallon or the pond for at least 3 years, so will this affect their growth, or will they keep growing right up until they're swimming around the tank with zimmer frames and moaning about the young 'uns?
