Another none salt related question - At what point would you recommend adding a pleco (algea eater) to the tank?
Plecos are one of the first fish, many, people want to keep. however more experienced keeper, sometimes suggest, it should be one of the last. Firstly, the "common," (actually, there is no such thing as a "common". its a term used to cover, several "breeds" of plec) all of these can reach 12 inches. some 18 and one that will, kept well, reach 24 inches+. they are a filthy fish. requiring good filtration and, in truth, a mature tank. ok that's the technical bit, now reality, they aint algae eaters! they do eat it. but, in truth, they are an omnivore, requiring protein and veg matter. they are also known to get "grumpy" with age. getting territorial. a pleco that does eat algae is the BN,
Ancistrus cirrhosus. its a fascinating, if not to say, odd, looking pleco. they grow to, around, 4 inches. given the chance, and a good keeper, they breed like heck. again as a, scale-less fish, i would suggest you wait till your tank is mature before adding one.
the Siamese Algae eater
Crossocheilus siamensis, is also worth a look. take my advice and avoid the Chinese Algae eater
Gyrinocheilus aymonieri. its a bad temped
, and aggressive fish
. that
, eventually, looses its taste for algae, and goes after the slime coat of its tank mates
