I do strip tests for hardness, nitrites, ammonia etc. Every time I do water changes. But they seem stunted for no apparent reason.
liquid test is more accurate than strips

You sure these are giant gourami and not something else? I've seen massive ones in swamps with stagnant water.
They look like giant groumi (coloration and patterns) and they're behavior matches
I seem to recall that many years ago there was a member of the genus Trichogaster (I think...) that had several common names, and one of them was "giant gourami". They only got to about 4 or 5 inches, so the name never made sense to me. They looked like somewhat drab, larger Dwarf Gouramis. Back then the true Osphronemus was not seen much in the hobby, at least not up in Canuckistan. Asesoxlucius stated, true Giants don't have much for colour or pattern at that small size.
Really need a pic.
I think it was the India giant gourami (Trichogaster fasciata), which just grew over 4". I also found it weird that its common name was Indian giant gourami when it nowhere near the same size as Osphronemus goramy.
