I’ve lost 4 neon praecox and 3 bosemani (all mature fish), over the last week. One each day! They all appeared healthy (except following note) and didn’t exhibit any lethargy or anything. The corpses all showed a patch of pale scales at different points on the torso. I noticed that the last bosemani to die had what looked like a small gash in his scales right behind his head. I can think of no explanation as to how he could have been physically damaged. When I found his corpse the scales around the “gash” area were pale.
Other inhabitants of the tank include lots of cories, cherry red shrimp, 5 hatchets, 3 zebra plecos and a gold nugget pleco, some gold white clouds, a couple of mollies and a sword tail.
The tank is heavily planted, but I’ve been struggling with poor plant growth problems for months. I’ve been dosing traces regularly and some macros once or twice a week.
It’s so weird that only the rainbows are dying and one day for a week and nothing else seems to be having problems. It’s also a sudden death thing, usually during the day while I’m away at work. I only have 4 boesmani left.
Thoughts?
Thanks,
John
