when I was really in to my tanks had two grow from 2.5" to 8.5" over the course of about 8 months or so. miss those fish, broke down the bigger tanks when I went saltwater
If your senegals are failing to grow you most likely font have a large enough floor space for them to swim along, not chaninging eater often enough, improper feeding
I agree with this. I have an 7-8" senegal that I bought from a lfs at 3". 29g for a month, 75 g for 2 years, now in a 180. I dont want him but cant bring myself to get rid of him because he was the first fish I ever bought.
