mine took 2 yrs to grow this big
but some get stucked at 7-10" wun grow bigger
those i think is due to too-many-tigers-in-tank-syndrome
then the fish all release feremones
only the alpha fish will grow pass the rest
i believe if wanna have my other tigers big need to find another tank to place my biggie
then the fish will fish to be the dominant piece
but sadly house no space for oanother pred tank + personally no money =(
ur 2.5" IT good luck with it
train it to take SW cos SW is damn good for growth imho
i used to train my tigers on SW before anyting else then into MP
and most of my fishes are FAT and overweight like me
yup i have four tigers
2 IT 1ST 1 NTT
used to have more
but now only 01X 5ft tank
