i test water weekly- and i have always done this, the water conditions appear fine, and no other fish have gotten ill or died. it was very strange when he died. he didn't look sick. he was big, so its possible he just died of old age. i've had him a while.
nitrate- yesterday was 0ppm, but usually fluctuates between 0 and 5ppm.
i do a 30% water change weekly, and every other week, i do an additional 50% to keep nitrate low.
i was having trouble uploading pictures, but there is plenty of swimming space in the tank- since i know all my fish require a large area for swimming. i've had almost all of these fish a year and a half, and they've been very healthy. none of my tiger barbs have gotten much bigger than when i bought them, they are about 1.5 inches each, and have stayed that small so far (1 1/2 years).
i have an external power filter, that was made for a 50 gallon aquarium- i don't really use the carbon inserts, just the material to catch debris. its got a biowheel.
i feed the fish vegetables, flakes, brine shrimp- etc (not all at once, hahaha- on a rotating schedule.)
they all seem happy and healthy. i was going to upgrade to a larger tank eventually, as they grew- but then they never really got bigger.
but if you think i am at max capacity, i will definately not add to the tank until i get a larger aquarium.
