Personally, I think it's more of a cultural difference, myself. Most of us grew up with the "goldfish in a bowl with cheap gravel and plastic plant" environment and it's hard to get rid of what's considered "tradition". Also explains why a lot of people use carbon. Because we always used carbon and that's how it was done when we saw someone else's set up. At least that's what my husband and I thought. When we found out that most hobbiests don't use carbon, we were aghast. What?? No carbon! But we ALWAYS used carbon! No aerator? No bubbles? But the fish will DIE!!!! Things like thatniethammer said:Hi Xielos,
are plants very expensive in Your country? BTW, You can use also homemade bio-CO², that costs you just a few pennies, it should be less than 2 $ for 2 month. But You don´t need necessarily CO², sometimes, depending on Your water and Your plants, it will also do without.
Niethammer, do you have links to some of those NG biotope tanks? I'm working on the plans for a Boesemani 90g in April and I'm thinking of either a 55 or 90g one for Glossolepis pseudoincisus. Gotta have that FISH!
