Hi Krich...
The 2 large Indos I've been with me for years now..4 and 5 yrs roughly.
They have totally opposite Indo shapes.
One is high back very deep bodied with high angle slope to head.
The other is more like a bullet shape... Longer and not as deep bodied. This oddball one is close to 18 inch... But the high back Looks bigger and bulkier..
I watch them a lot ... And often they swim together like pair..maybe the polar opposite shapes could mean male and female...... So I get excited....
But other times I think ,....this can not be when they highback dominates as alpha fish....
