Algae eaters in a tank at home isn’t just a tribute to fashion, it’s a necessity. They help fight unwanted inhabitants on tank plants, glass, decorations and substrate – yes, I’m talking about excessive algae amount in a tank. In any, even the best managed tank, there are always some algae, but usually their amount is small and they are noteless against the other higher tank plants background.
The decision what fish should be the first in your tank can be both a spontaneous and a deliberate one. Sadly, the beginners often follow their first impulse and buy a fish without knowing anything about it. And after that instead of happiness and joy they get “headache” and troubles. You should choose a fish thoughtfully, because its life and your comfort depend on it. Before going to a pet-shop or a market study all available info about the fish you’ve enjoyed.
All beginners in aquarium husbandry often grope in the dark not knowing what fish exactly they want to have in their tank.
On seeing a small and cute suckermouth catfish in a pet-shop they don’t even have a clue that it’ll grow to be over 30 cm (12 inc) long and live over 20 years.
