I have a question about my plants...
We have a 5 gallon tank with aquaclear mini filter, heater and lighting (1 10 watt CFL and one 25 watt incandescent bulb on the list to be replaced). The tank has gravel. Lights are on about 10 hours a day. I had baffled the filter to reduce turbulence for the fishy...
One betta living in the tank since mid June.
On July 22, I planted a Java fern and 2 anubias, one smaller one that had flowers and 1 larger one, with the leaf stems about 5-6 inches long. I did not bury the rhizome but some of the roots were down in the gravel. The larger anubias anchored to a piece of driftwood and the smaller anchored to a small tank decoration. Oh, and there's some java moss in there too. I also started using Flourish.
About 2 days ago I noticed a white "fuzz" on the rhizome of the larger anubias, and one leaf had broken off at the base.
Then I noticed the same fuzz on the smaller anubias yesterday, with some leaf breakage. This plant also had what looked like some brown algae growth on the leaves.
Java fern seems ok, with some small patches of the brown algae looking stuff too.
Today I did about a 40% water change and took out both affected plants. The large anubias rhizome appeared to be completely rotted and stank.
The smaller one had a piece that seemed to be saved (still green, firm, not smelly), so I washed it and re-anchored it making sure rhizome not buried at all.
Water test today shows pH 7.4, ammonia 0, nitrite 2ppm, nitrate 5 ppm.
What did I do wrong with these plants? Or is it possible that there was something wrong with them from the start? Has the plant rotting affected my water test levels?
Thank you in advance for any insight!
