WOuld you beleive it Cane, you bought my old tiger which I off loaded to the LFS, last week. I've had him for 4.5 years, and he's been dark for 90% of its time. Only until recently he went really white after I added a load of stable tigers. Still he did not stabilise with black bars and gold base colour. Not like in yout tank. Looks fantastic.
Any how, I.m glad you picked him up and at least the LFS did overcharge some innocent customer.
AMazing how Indo Tigers can really change depending on Tankmates, and tank environment. Still cant beleieve after 4.5 years, move him to your tank with Arrowana and stingrays and Bang: looks wicked man!
Also, when I moved him, I have another 9" IT which ws allways bullied and black. This one is now Super Stable.
(in the pics with a slightly orange base colour) I guess its cause I moved the bigger one.
May be you can trade me some of your tigers, and see how they react to my tank....
