values
thanks for that reply. pH and amonia are all within the normal range, havent got anything for testing nitrite/nitrates yet, as pet shop assitant didnt ask me to get them. if they are important, i will go to get some!
the hoplo cat's body just turn pale a bit. i didnt want to take him out so my flatmate did. but i didnt see anything unusual on his body at all! neither on the dead green fire tetra. i have lost 2 green fire tetra last week!
the female gouramis' dorsal fin has got white stuff on it, i think it's fungus. i got some of those blue remedy for getting rid of white spots so i tried last night but my khuli loaches got all creazy and turned pale because of that and turned ill! so i had to quickly change some what to dilute the water and later on they calmed down. i think i have to put the gouramis into a seperate bucket to do that.
the weired thing about it is apart from the sick ones, other fishes in the tank all seems pretty healthy and happy. but just all the sudden they turned unhappy and i dont know why!
tank: 20 gallon
black neon tetra: 11 (2 died)
green fire tetra: 11 (2 died)

water change: every tuesday and friday night, 20%, always mix stress coat with new warm water
chamical: periodically some chemical pills in the filter to remain water crystal clear, and little bit of waste control liquid (never too much though)

so where is the problem? im afraid today when i get back home from office, my gouramis will be dead already! :sad:
