Considering Tangs

cool, tangs are always a nice and interesting species to watch i can watch all of my tangs for hours and honest i do just that, but as for that 29gal you could go with a pair of julidochromis species transcriptus being a tad bit on the smaller size with juli's and a colony of shellies like neolamprologus brevis, multifasciatus and a few others, a colony of multi's will be nice plus they are like rabbits you twitch your eye and there are like 15 babies already plus they mesh well with the transcript's aquascape your tank with one side full of shells and the other side with creek rock forming caves, your shell yard should be like 2 to 3 shells per fish ratio so they have ins and outs so to say, as for top water in a small setup like a 29gal with tangs your very limited on that issue if you just need to fill the top with a fish you could try a trio of praecox rainbowfish they are fast and only get to the ripe size of 2 inches which is what multi's reach and the transcript's reach like 3 1/2 inches dont feel compelled to add cyprichromis sp. they will not fare well in a 29gal, hope this helps, take care my friend..

oh yeah snails are a personal choice some tangs eat them some will ignore them

if i had to pick i would pick the shellies just something about them jumping shells fascinates me hehehe well not much fascinates me anyways these days, hehehe
