blue gouramis get up to 6". what you cant read on most information sites is the older they get, the bigger they get, the more aggressive they get. they can also end up being very territorial ecspecially if your tank does not get switched around or addition and decreasion of fish all the time. ive kept blue, opaline, and gold and about 2 of each at different times and some together. they are semi aggressive at youth but when they start getting 4-6" there aggression level seems to get very high including with new additions to the tank.
waiting to move your fish until they become established in that tank is a bad idea. the older a fish gets and the bigger they get, the more stressful and chances of death become upon it. moving them as juveniles is much easier. ive moved juveniles the same way i have adults and ive had lots of adults die but no juveniles. plus the stress it takes on them trying to catch a large fish.
i would rehome as soon as possible. how long have you had your tank set up? also they always say a. use a liquid test kit and b. ALWAYS test before water change so you can get a true reading on what the fish are going thru therefore you know what you need to do to get numbers correct.
also about ammonia readings reading zero meaning that it isnt cycled yet, that is also incorrect because my tank has been set up for 2 1/2years now and i have had zero readings on my tank before.
you post very good information on your posts and you are very detailed and sound very intelligent but i would honestly listen to all of these guys/gals of their advice of getting rid of ALL large fish that will outgrow that tank asap and then you can get some others. right now you may not be overstocked on size but bioload you are.
and yes NEVER LISTEN TO PETSTORE EMPLOYEES, find a few different ACTIVE forums and get some advice from the people because they will not give you incorrect information and they will share there experiences with what happened with the same type of fish.
