thanks for the write up tetrabotia. is a snail better with the algae than a pleco?
That might depend on a few factors- but my point was more that you (anyone) should get a Pleco only if you
really want that fish,
and you have the room for one- not simply because you (or someone) needs an algae control fish (or algae control creature).
For example- in your question, if someone had a 90 gallon tank, AND they need algae control, and they
want a pleco, I say get one. You may still need other helpers with the algae (including water care), bu under those conditions, a Pleco is not a bad addition.
The antithesis of that is someone who has a 20 gallon tank, is moderately stocked, and decides they want something to help them with their algae. The LFS guy/gal suggests a pleco... that nice young one looks good and small... and if both dont have the experience to question tank size or current bioload, bang! Another Pleco winds up somewhere it should not have.
So if I had a 10 gallon- would I prefer snails of some sort over a Pleco? Sure, but keep in mind the snails might still not be the best choice. In the 90, I might prefer to add a pleco, as long as it fit all of the other particulars of the tank (i.e., I would not put a Pleco in a heavily planted tank that has the goal of looking like Amano's tanks...)
It is almost impossible to eliminate algae, but it can be controlled very well. I clean for algae on the viewing surface of the tank only (nothing else has enough on it to be noticeable) about every 2-3 weeks. Lighting (duration and intensity), proper bioload and filtration for the bioload, plants (if you can have them), proper feeding levels, and the right creatures- all go a long way toward conrolling algae. Other than that, checking for nitrates and phosphates and changing water appropriately is all that is needed beyond that.
