really? someone mentioned butterfly plec to me the other day? my other halfs dad has one we bought from the same shop at the same time and it's over twice the size in length and width now as ours. needless to say im slightly jealous but also confused. theirs is in a smaller tank than ours and yet has obviously not had its growth stunted. our tank is twice the size of theirs easily. so why is mine so small? we feed algae wafers. they dont. what breed could there's be? looks almost identical apart from size and the dorsal fin looks smaller?
His is most likely to be the same species,
what are your water stats? maintenance and feeding regimes etc?
The growth rate of any species is greatly effected by the number of water changes done on the tank, the types of foods given to the fish, and the stocking levels of the tank in question
