Very nice fish there mate! I got the exact same stock in one of my tanks lol, two syns and one thai silk. Are your TS aggressive against his tankmates?
I actually have the Titanium Flowerhorn in a separate 45 gallon tank by himself. I did have a female for him to breed with, but he ended up killing her 2 mths later. The Synspillums are in a 125 gallon. I have 5 of them, 2 pairs and an extra male.
