Some fish questions -- Are these things true?
Recently, I have read some things that I'd like to hear more about. Here they are:
1. Some breeds of dwarf angelfish can be kept together. I was under the impression that dwarf angelfish were dangerously aggressive toward one another in captivity. Nevertheless, I have read that Half-blacks and Lemonpeels can live well together, if they are introduced at the same time. Is this true? If so, are there other pairings or groupings that tend to work well?
2. Very red Flame Angels were probably caught using cyanide, and are likely to die quickly. Is this true? If so, should I be suspicious of ANY very red-looking fish -- Flame Hawks, for example? Also, can anyone think of a good way to decide what's VERY red?
Thanks in advance, as always.
