Thoughts on dying fish
Tank size 20G
These parameters have been consistent for the last 2 months at least... I noticed last week that 2 of my neon tetras had disappeared. I'm assuming they died and decomposed before I noticed. Then, yesterday, a glowlight tetra and my favorite fish, my GBR died. These fish were all in my tank for well over 6 months. There was no outer sign of illness, but I did notice that my glowlight (who is fairly large) had trouble swimming straight. He would kind of sway side to side. My blue ram is always hiding, but her color has been very vibrant and she showed no signs of distress. The only thing I have noticed is it looks like there is a fair amount of slime coat floating on some of the plants and gravel. I don't know if this is an indication that that were stressed or sick. Any thoughts on the sudden death of these fish? I do water changes 30% every 10 days. I have 2 penguin 150 filters and the water is clear.
Fish left after deaths:
5 Neon Tetra
I"m sorry about your losses.
The first thing that comes to mind is that you should up your water changes. 50% weekly minimum.
what type of water conditioner do you use? Do you vacuum your gravel and if so how often?
what are you using to test your water? strips or the API liquid test kit?
Do you use any other additives?
have you added any new fish lately that did not go through a quarantine period?
all of this could help determine what's happening.
