Aquarium Advice Addict
Only 2 years?
I've had a really healthy tank for 2 years, no incidents of ammo/nitrite spikes, no algae bloom, no illness running through the fish.
But recently I've been losing one glow light tetra every 10 days or so.
Two harlequin rasboras too.
They decline very slowly, each in a different way. They just start swimming less well and their colors fade. Some end up at the top, some at the bottom. I scoop them out into a quarantine tank and have tried various remedies. Fins, eyes, body, scales look pretty normal. One had a bendy spine for a few months. One got a cloudy body maybe 9 months back then regained translucence (that one is bobbing an inch below the surface now, paddling in circles, he's looked a little sideways each morning when the light comes on).
Tank is planted 56 gallon column. I've always used Seachem equilibrium and cichlids buffers to get KH and GH up to about 4 each, so water is still soft. 78 degrees. Water changes, water tests with APi Kit, the works. Fish less cycle before introducing fish. I've never seen a trace of ammonia, ph steady at 7.8, nitrates 20, nitrites zero. A little Excel and Flourish. Two canister filters (total of 100 gallon capacity).
Danios and 2 angelfish are doing fine. They don't pick on the tetras either (and the tetras have lots of hiding places). When I find a tertra seriously struggling the angelfish watch it curiously for a moment, once an hour, but stay back, then go away.
All I can think of are ... The glow light tetras are stressed because their numbers are dwindling. Or, these are the only fish that came from a big box store instead of LFS so maybe they're a little inbred or less hardy or something.
