Buy tank then fish

[hooliganATV]

I have to say, there are numerous critters of all families, orders and classes that will not feel at home in a very large tank. I have a much more vast knowledge of snakes that this affects than fish, but it is a good "middle-ground debate" .....I agree some fish, especially as juveniles or intermediates are better off in a smaller to moderately sized tank, but the big question is "Which ones?"

i had written a lengthy reply about how snake forums are the same yet most of the time the people saying vivs aren't big enough don't have a clue as alot of snakes prefer small spaces and stress in large quarters, but i deleted it. sometimes it just takes a bit of research into the fishes habits as opposed to habitat

 

[ehh]

But even if any animal does better in "smaller spaces" you can mimic that in that large environment. You have to set up the environment with lots of hiding places.
You'll never convince me that an animal will thrieve less in a larger environment. It may be boring to but that's your problem lol.

Don't think you can compare fish and reptiles on this, reptiles on the most part can be taken out of there vivs my wife would moan like merry hell if I flooded the front room to give the fish a swim out. No body has a problem with people how grow fish out in small aquariums,, just alot of people come on here with juvi dovii in 55 gals with grand plans to build 2000 gal tanks in there bedrooms for £4.

I bought four Goldfish for my 75 gallon fish tank a few years ago and these four goldfish have grown into real monsters growing past eight to ten inches long and the 75 gallon can't handle the bio load on it. So I'm in the process of upgrading the tank to a minimum 150 gallon and I might even go as high as a 220 if I'm allowed to.
