Re: Best Algae Eater for My Tank?

Part of the problem with a bristlenose in a 20 is that it is just too large a fish. No matter what they eat, vegies or algae off the sides of the tank it will all become waste. There is not a lot of protein in vegetable foods, but there is enough, and the decomposing waste is indeed too much for a 20 gallon tank. I have not had the problem of bits of vegies clouding the water. My fish seem to find all the bits and turn them into fish poop.
Here is what I would do, if I wanted to keep the fish in the OPs list:
Botia kubotais- These guys get pretty big. A group of half a dozen would be OK in a tank at least 4' long, 45 gallons They may hide well enough to keep out of trouble from the Tiger Barbs, and a 45 gallon tank is large enough for a Bristlenose Pleco. They are gentle fish, so a different schooling fish would also work. I have Clown Barbs and Rainbows with mine.
Pangio oblonga- OK in the 20, get at least half a dozen. Add small schooling fish such as Rasboras, or Puntius pentazona. For algae, a trio of Otos.
Puntius tetrazona- These guys get big, and can be too nippy in small groups. Put a dozen in the 45 gallon tank.
CAE- Return to the store. I have heard of them being useful in a tank of African Cichlids, and even then I knew of one that was so aggressive it ended up in a tank by itself. They get larger, too, so 'a tank by itself' could become at the absolute minimum a 20 gallon.
