This stuff must've grown overnight because I haven't seen it before today. I dunno what it is, if its algae, bacteria, good, bad or what. Take a look:

Thanks.

That gunk is just a buildup of dissolved organics that are solidifying, such as fish poo, excess food that decayed and dissolved into the water, etc. Another sign that PWC's may need to be made more often, or not gravel vac'ing enough. How old is the tank and what's your maintenance schedule?

yeah i think im overfeeding a bit. I try to get enough food in there for everyone and probably get a little too much in there. but theres never really much left in the gravel cuz the rams peck it out throughout the day. I'll try feeding once a day and see how it goes. Thanks
