I am currently runnig my tank at around 21 degrees. I collect all my livestock, but since i live in cape town, travelling to the warm seas to collect is starting t oget expensive.
Do you think any reef fish that LFS sell will thrive at 21 degrees?

i enjoy collecting my own livestock and am particularly facinated by the southern cape coastal life, the whole two oceans meeting etc. If i run the tank hotter things die.

i know some of the wrasses and butterfly fish survive at that temp, but not sure if keeping them at 21 permanantly will be a good idea.

459b - it should not be a problem if you investigate the life-stock you are planning to purchase.
Most fish should be able to adapt, given that you acclimate long enough (3 to 4 hours minimum).
Corals, nemmies and other inverts are another story. They will most definitely NOT survive!
