a 55 is a decent tank. But it is still far too small to keep the fish you
have. And the filtration will need to be upgraded and probably the heater
for that size tank.
the thing is, once you start down this road you will want multiple tanks
anyway. Just keep the 29 for some small fish. If you want to keep your
current fish then start thinking about a minimum size of 150 gallons or
larger.
