mine slow... but i quess some grow faster then others.... depends on many things.. but i think ralatively speaking it would be concidered a slow grower..
Fast..Unless they're in a small tank...I have 3 Senegals all were same size 3 inch...2 are in a 55 gallon and 1 is in a 20 gallon..The one in 20 gallon is still the same size while the 2 in 55gallon are double the size or more.
Small tanks stunt bichirs. In a big tank with good food they will all grow quickly. What size tank is yours in and what othre fish are in there? [dare I ask...]
