I've noticed earlier that some of my Gouramis started to spend more time at the bottom of the tank. Now all Gouramis are spending most of the time hiding. Even Bolivian Ram, the oldest and healthiest fish in the tank, swims less and spends more time under leaves of banana plants. They do come out to eat and have good apetite, but several minutes after feeding, they hide again. Here is some water parameters:
temperature - 79
pH - 6.0
amonia - 0
nitrite - 0
nitrate - 20
These parameters have been quite stable for last 4-5 months. One of my Gouramis flashed against rocks as if it had some parasites. Besides that, all fish looks healthy. All fish have been in my tank for at least several months (no new additions).
I have no idea what would be a reason for this. pH is quite low for community tank (our tap water pH is 6.6), but I don't think that Gouramis could have bigger problems with that. What could it be?
