I have 2 Oto Cats in a 29 gallon tank that have found a favorite spot and don't move from there. Both Otos stay behind a java fern I have in the back corner of my tank. When they where new to the tank a they were very active cruising around from plant to plant and hanging out on the drift wood. they have been in the tank for 5-6 month. Both look very health but do not come out from behind the java fern as they did before. When they were active they kept the plant leaves clean and free from any algae. Would adding a couple more coax them out?

Will do, Thank you again Roy. Definition is spot on "initially producing a wet, dark-green, "steamed" appearance"

Thank you Roy, I have seen no Ammonia spikes that I am aware of. I do not gravel vac as I have a medium grain sand substrate. Crazy because these Crypts showed very little melt when converting after planting and have always been "healthy".

have some established Crpyt Tropica that has been having this strange melt issue for a while now. Trying to figure out if its a deficiency. PH 7.5-7.8, GH 75-100 ppm, KH >150 ppm, Fertilizers Easy Green Root Tabs and Easy Green Liquid. You can see in the picture a green spot about 3/4 of the way up the leaf, this spot will progress for 1-3 days across the leaf until it detaches. You can see the progress in the photos this pics were taken within a day of each other.
