Very expensive to gamble indeed. Many vendors offer them but it appears largely seasonal and the season is running out if not over by now.
Wes still has tigs at $175, last time I saw. Most others offer them at $250 give or take. Some want over $300. Some, like Fish Bolz Atlanta GA sell them for $125. Draw of luck.
Jurs have been strange. They used to be ~$40-$50 fish, nowadays I see people asking 2x-3x more for them. IDK what's up with that!
I got 10 jurs from snookn21. And 10 tigs - 4 from Manny C. on MFK, 4 from Fish Bolz, and one from Wes, and one from Shark Aquarium but it closed.
They will fight if together. More or less they will. Sooner or later the fighting will turn serious. There are exceptions. MFK member
