T5 tubes will only work in a T5 fixture. If the fixture is T8, which is the "regular" type, then only T8 tubes will fit.
Aside from this, T5 HO tubes are considerably more intense light than the same type/size in T8. And this can affect fish. You can read more on this here: http://www.tropicalfishkeeping.com/f...er-fish-81982/
Assuming you have a T8 fixture, good tubes would be tubes that are cool/full spectrum as these will bring out the natural colouration in these beautiful cichlids.
