I would NOT try antibiotics. They don't work on all types of algae, and will seriously mess with your water chemistry and your fishes health unnecessarily. It looks almost like a brush red brush algae. This might mean your pH or carbonate hardness is too high. When i had black brush algae, I took the affected plants out, sprayed them BIREFLY with hydrogen peroxide, rinsed them off VERY well, and then put them intoa  quarantine tank for a couple months. It took a while and the plants looked like h*ll for a long time, but the algae died off and the plants recovered. I have a very heavily planted 180 gallon freshwater tank.
Siamese algae eaters MAY eat it, but I have 4 and they never touched it (but mine are spoiled and eat mostly blood worms.) ;-)

These algae are brown, not bluegreen (I attach the photo again). I may try antibiotics.
I think I could not have shrimps, because I have Botia fishes in my aquarium and they probably would bite off their legs,
these Botias not once ate smaller fishes' eyes.
Other fishes don't eat these algae, even the Silver Dollars (Metynnis sp.) which ate almost all plants I had except Microsorium sp. and two small Cryptocorynes. Other plants were immediately eaten by the silver dollars. I had also a fish called commonly in my country "lawnmower" (Crossocheilus siamensis), it was eating these algae, whe&#1352;č&#

If it is a cyanobacteria (bluegreen algae) they can often be killed with a good strong dose of antibiotics. The antibiotics usually leave the fish and plants alone.
You might also try algae eating shrimp. These are freshwater shrimp in the family Atyidae, in the genera Caridina and Neocaridina. These animals have brushes of setae on their claws and use the brushes to scrape algae and periphyton from the substrates. They can be amazingly effective at eating green and some brown algaes, but they will not touch cyanobacteria.
Good luck,

Are the large plants (like Colocasia) in pots?
I don't think they would grow good in so shallow gravel.
What fertilizers do they use?
I also have a problem with long brown algae in a classical aquarium,
any fish doesn't eat them, and I don't know what to use not to kill plants and fishes.
The algae grow on everything, on plants, wood, stones and even on glass.
I reduced the lighting form 60W to 30W, but they still grow slowly killing the plants.
The dimensions of my tank are 100x40x50 cm (40x16x20 inches) - about 200 l.
Can anybody help?

I posted a note a week or two ago about Devin Biggs' aquatic aroid website.  These are some of his newest photos of a 65 gallon tank:
He said he thought the tank was looking "pretty good".  I'd say that is a major understatement!
Devin will be at=2
0the IAS show in Miami next week.  If you like to grow aquatics you'd be wise to find him!  
I promise I will!
