So far the corals are doing really well since it's winter here in Australia, but like I said before, I wouldn't worry too much about heat issues in summer as these were collected from places where the conditions are really harsh, with temperatures going as high as 39° in midday, and as low as 18° at night. I'm only having relative success with the fishes though, in the begining, I pretty much try to catch everything that I see (a little kiasu), the result is uncompatible fishes or fishes that're too big/old to adapt to captivity. These days, I try to get smaller and younger fishes, as their more adpatable to changes and their diet are more varied, making it easier to get them to feed on frozen or self prepared food. I also try to do a little research before each trip to decide what to catch, even if it means going home empty handed. When I do get fishes, I put them in quarantine, that has a few permanent residents so that the new fish will learn from them how to feed on frozen food. If I'm not able to get them to feed with 10 days, I'll bring them down to one of the senior member's place who seems to be able to get almost any fish to eat.
