Alright, this is about as good as I can get with my severely limited equipment. I am going to try to provide everything that will be relevant starting with water parms.
tank size 10 gallon
Ammonia & Nitrites = 0
Nitrates = < 20 ppm (strip color change doesn't happen until 20)
ph = ~ 7.5ish
Gen Hard = 12
A weekly water change happens regardless of nitrate reading. The amount of water changed ranges from 20% to 40%. The occasional vacuum will happen but never all of the substrate at the same time. Biomedia is never completely removed and as stated in my first post this tank gets about 12 to 14 hours of light to facilitate algae growth to feed the inhabitants. Approximately 1ml of seachem flourish is given during the water change and water is chemically aged with a tetra de-chlorinator.
At least 50 red cherry shrimp by now (they are breeding like cockroaches)
3 otto catfish
2 small gold mystery snails
2 black mollies
Here are the best pictures that I can get with my droid:
Picture 1: Just a good overall picture of what I am seeing when I look at it. The behavior of this stuff seems to remain constant as in there is none of it free flowing in the water and it is seemingly adhered to the individual strands of the marimo moss. However, I do also see a few pieces forming on nearby java moss and hornwort. In both instances it is stuck around a leaf or stem.
Picture 2: This is the closest I can get without pixilating the image. As you can see there are what looks like mature instances and you can begin to see some more developing to the right of the established "colony".
Picture 3: Just in case someone wanted to throw in the token snail eggs response I found a cluster of common snail eggs not far from my strange new growth who I am now calling Steve & co. You can see my mystery fungi/mold is much smaller.
Picture 4: Overall of the tank to demonstrate water clarity and plant life in the tank.
I really hope this helps someone draw a conclusion as to what I am dealing with. Its growth pattern somewhat indicates that it doesn't go water borne to land and start a new colony because this outbreak is only happening in one corner of my tank and trust me I looked everything over with a fine tooth comb once I seen this intruder, I mean we all do don't we? Tufts of it are bigger towards the center of the outbreak and smaller on the edges.
Hope this helps.
