That's black brush algae (aka BBA)... so far the only fish known to eat it is Siamese Algae Eater (SAE).

Yeah, yellow algae eater is not siamese algae eater... the yellow ones are different species and don't eat BBA.

Depends on the type of algae... if its the soft green or brown film algae, then otocinclus will eat that.

If its hard green spot algae, then nerite snails can help, though established algae spots that are too tough will still have to use algae scraper to manually remove.

If its those fuzzy type, look like green fur on the glass, then shrimps can help eat those (efficiency depends on the algae growth rate vs hungry shrimp population).

For a well balanced tank, cleaning the tank glass every 1-2 months is quite normal.... but if you have to clean it every week or every few days, then better check your lights, nutrients and Co2 parameters.

1 to 2 time per month is ok for me. But i notice the grown on my fish tank. It is greenish spot, but can be easily scrub off. I have nertie snail, amano shrimp and otto. But seem like not really working well.
In fact, i have 8 amano shrimp, 5 otto, 2 small nertie snail. They seem chewing my rock instead lolz.

Anyway i had brought the timer, i try to limit the lightning duration to 6 hour daily, previously like 10 hour.

Yeah, green spot algae is perhaps one of the toughest algae to solve. So far the only creatures i've kept that have an effect are nerite snails, they can minimize it by eating the fresh growth, but still not 100% eliminate all of it.... maybe if the whole tank is crawling with dozens of hungry nerite snails then can see greater effect.

Ts, by the way, this is chinese algae eater. Rather aggressive type. When they grow older, they will attack other fish and not eating algae. I had bad experience on this fish. It kill my barbs right in front of my eye !! I faster remove it. You google it, top 10 worst community fish !

The black brush algae is due to low or fluctuations of co2. Usually affects the dying plants first.

You can put seachem excel directly and it will turn to pink or white where the shrimps will finish it off. But the best way is still prevention.
