when I bought my 5 I didn't know what Sumatra had to do with it, I knew they were Dats all hiding in a big tube in a dark tank $38.00 ea. I had lots of questions like why they so dark, will they get lighter, what they eating(worms)...there were 12 I bought 4 then came back next day got another, only two left some one else bought 5...didn't want to crowed my 150 gal. Funny after I saw the post on here about breeding and being plentiful in U.S. I called lfs to see what they had, siamise tigers about 1-1.5 in $269ea 10 instock, 3 bar indo tiger 3 in $300 5 available. Crazy..sombodys making money.I was just wondering if any shops you guys frequent note the distinction between the two variants?
