I have a 28g nano, so very similar in size. To be completely honest, I have two clowns, a flame hawkfish, and a purple pseudochromis. I feel my tank is crowded. I notice the lack of swimming space and every once and a while, I will notice a bit of frustration and aggression. I would most definitely not put in the six line and flame angel. I would pick one. Then you should be okay. Down the line, I am positive the six line or flame angel will flip a switch and become extremely territorial and aggressive. The six line is probably a bit more dangerous. However, a 32 is a bit small for a flame and may become aggressive over time due to the small swimming space anyway. I recommend 50 and up for dwarf angels and obviously proceed with caution if you are going to have corals. Some will also chime in about their horror stories with six line wrasses going rogue. Hope this info helps. Might be better off skipping both the flame and the six line. But I would most definitely not do both!
