Hi there, I added 7 fish over a few weeks to my 160l tank. I have cherry barbs, angels, dwarf gouramis, 1 redspot, 1 bristlenose, one loach, one rainbow shark.... I think thats it?? oh and a pair of sword tails.
I have a fully covered tank and no toxins sprayed in the house.
I will do water change, gravel vac and get water tested, was fine not that long ago?
Below is a pic of my poor algae eater and one of the male cherry barbs...
