I am a pretty experienced aquarist, and I have never seen this before.
My tank started life as a 10 gallon nano. I was keeping really hardy stuff bacause I travel quite a bit.
One finger leather specimin
Purple mushrooms
Green speckled mushrooms
Green Ricordia mushrooms
Lawnmower Blenny
Royal Gramma
One blue leg hermit
5 Astrea snails
One turbo snail
15 pounds of Figi rock
A few small to medium bristle worms
Over the last three weeks I have:
Moved everything to a 20 gallon long
Increased lighting from 30 watts to 80 watts (NO flourescent)
Used local tap water for large water changes. My tap water sucks but has never been a problem for this tank.
Added two rocks with a large number of brown "fuzzy" mushrooms.
Since I have had such great luck with the mushrooms previously I thought it was a no brainier to add some more. I have tried to keep water flow gentle and lighting somewhat subdued. My older specimins get HUGE and are shedding little clones everywhere. I thought I had stumbled onto a formula for happy mushrooms with low light levels and minimal current.
I left town for 4 days and returned to find my purple and
green mushrooms rotting in the tank. I do not know if the other mushrooms are soon to go but they do not look full and extended. I have removed all of the "smooth" species that were troubled. I have not removed the "fuzzy"species that seem to be working out better. The verdict is still out on any of the mushrooms but I am hopeful that a rather agressive water change (30%), skimmer and filter cleaning will get the tank back on track. The tank actually smelled! I am not getting an ammonia spike yet but I am sure one is on the way. The newly cleaned skimmer is foaming like a cappicino machine since I hooked it back up this morning
I lost about 40 mushrooms and have another 45 at stake. The leather is doing great.
The newest brown "fuzzy" mushrooms never really showed me the vigor that the other specimens displayed. I chalked it up to a less than ideal life style in the LFS, etc and figured that a few weeks in my tank would show some improvement. Could it be that they carry a mushroom eating bacteria or virus? Is this chemical aggression? Any information that your group can share with me would be useful.
Thanks a bunch,
James
