My fish tank

[9y]

Will they die?

Yh not enough O2 will diffuse into the water

What if i just let some water out so the surface of the water is bigger?

[kk.]

Still not too sure. Its the fact that its not got a very big hole for air to get into it, so even when the wind blows it will be hard for it to get in

Hmm i'll have to find summit, they are swimming round the top alot. I'll see what i can do after work, i let some water out.

[kk.]

you could maybe have some plant life in there, that would give them a pretty huge amount of O2, especially with it being glass

Thanks for the tips

They seem alot more lively now i've let some water out, a woman at works giving me her old tank and filter n stuff so its all gravey as long as they last over the next day lol x

Good to hear. You don't want to kill the fish

Why not just but a cheap tank :S they'll probably die and then you'll have to spend more to buy more.

Surely you are not leaving them outside in the middle of a garden?
