I had a senegal, not albino, for four years before I had to rehome (long story) him and he only reached 9 inches in that time. However, he was kind of a rescue as he was missing both pectoral fins when he arrived at the store I worked at and was badly burned from ammonia during shipping. That may have effected his growth rate. But within six months he went from a measly 1.5 inches to 5 inches. The only thing I was able to keep with him that he didn't eat were clown and angelicus loaches. I had rosies in there with him for the first three months and didn't think he would be able to eat them as they were much larger than his head. I came home from work one day to find my school of 8 had gone down to six and "the friend eater" had two fat lumps in his belly. At this time he was only about 4.5 inches and the rosies were about 2 inches. . . so . . . ya. Rosies went back to the store and I tried scissor tail rasboras, as they were larger and faster and he ended up eating two of those after about a month. After that, I quit trying schooling fish and just kept to the loaches.
