Long time lurker, first time poster here ... I need some help!
I looked in my tank last night and found some kind of growth on the underside of the acrylic top of the tank. It looks like some kind of egg mass, but I believe it's too large of a mass to come from anything that is at present living (or has ever lived)) in the tank! The size of this mass is almost 2.5" long, and about 3/4" at the widest, and hangs down towards the water about 3/4 inches. I can see round shapes in it, fairly tiny. You can see them in the photo. The color in the photo is fairly accurate - somewhere between pale human flesh color and pink. The little bit of debris you see next to the mass is not from the mass -- little eggs are NOT breaking off. This is one solid slimy mass, all one piece.
In the tank are the following:
(2) male Gold Rams (approx 2" in length)
(10) neons ( < 1")
(1) mystery snail (1.5")
(3) blue long fin danio's (1")
(1) queen arabesque pleco (sp? 2.5")
(1) corycat (3/4")
(1) arrowana (some kind of twig shaped catfish, 3.5", but only about 1/2" wide at widest point)
Tank is 29 gallon (tall "bubble front" tank)
Live plants
Whisper internal 40 gallon filter
(1) airstone
NITRITE = 0.00 ppm
NITRATE = 0.0 ppm
AMMONIA = 0.00 ppm
pH = 6.8
TEMP = 78 degrees F
That's all that is in this tank. All fish are doing fine, water quality is good, We just cleaned the underside where this egg-mass or whatever is last Sunday, so it has been placed there within the last 5 days. We are SURE it was not there on Sunday.
Any help is appreciated.
