Fastest Growing Fish For Aquarium. The team of BRS made an experiment and the results. Also a bigger fish aquarium will not become dirty earlier.
Clown loaches grow very slow but become huge. If some stems are detached they will float and will not die so will continue to eat up Nitrates and help oxygenate your tank. All you can do it provide a large tank clean water and good food.
Plant growth can be accelerated by the addition of fertilizers.
It will be hard to shred or munch on so should live as long as you want in that environment. Best growth Ive heard for an rtc in the first year is 24 and that was with super power feeding. Fastest growing fish in the trade though is an arapaima. They are farmed for rapid growth.
