Given good water and nutrition, I thing the PBT is a hardy fish.

That being said, I feel a number of preconditions need to be met to insure success.

1. Don't be in a hurry to purchase one. They are delicate to poor collecting and handling. Shop around for a healthy one.

2. Look for a fish in the 3" - 4" size who is eating well at the LFS and who appears alert and undamaged in any way. In my experience, a fish of that size adapts to aquarium living well.

3. Place the fish in a reasonable quarintine tank with a sponge filter and some live rock for grazing. I treat all new fish with ProziPro for the first 5 days in quarantine.

4. If ich does break out, treat with hyposalinity. PBTs seem to be overly sensative to most copper treatments.

5. Keep it in quarantine for 4 - 6 weeks.

Given the tank conditions you already described, I think such a PBT will have a long and healthy life in your system.
