a 29 g tank for a dwarf angel (all types) is a death sentence so the answer is
NO
they are very active fish and swim constantly
the recommended tank size has changed in the past 2 years it used to be 30g or larger but since than it has been changed to 70g or larger as they are very active fish
here is the recommendations of live aquaria
I have both a coral beauty and a flame angel they are a hardy fish but at the same time they can be fragile fish !!
Let me explain :
1) they don't do well in newly established tanks as there isn't enough algae to graze on along with other inhabitants such as
pods
2) acclimation must be done so not to cause any stress as they are very temperamental with the slightest change in all parameters
3) dwarfs are known not to eat when introduced to a new tank and the death rate is in the 90% range from starvation
4) dwarfs enjoy live macro algae to snack on red grape/green grape seem to be there favorite , they will munch on other macros both red and green also but I find they lean more toward the grape macros , they will eat nori but they don't seem as enthused with it as live macro,
the problem is most don't like to grow live macros in the main tank
