ive been keeping a blue gourami since last year 2009 in a 2.5g tank. i know im not suposed to be keeping a gourami in such a small tank but the problem is that the gourami has grown to 7cm and i dont know what to do with it, please help me
I'm a little confused now: so the blue gourami is with the columbian tetras in a 10 litre tank, which is pretty much 2.5gal?
If you would like to keep it, you would need a much bigger tank. I think the minimum size for a blue gourami is 20 gallons, or about 80 litres. I'm not sure how the columbian tetras would work, I don't know anything about them. Is that what you meant?
