I have 2 females, both about the same size. I want to guestimate they are about 2 inches. I had a third, a male, but I haven't seen it around. At least it hasn't left the thick anubias driftwood feature.
I went ahead and took her out this morning and put a drop of melafix on the problem area for about a minute. She was in a hurry to get back into the tank. I also ordered some Fritz Expel-P, which is supposed to be Levamisole HCL. I never used it before but figured I better have it on hand, just in case.
After getting reoriented in the tank, she made a quick hurry back to the anubias driftwood. They used to live in there, as it was thick and I wouldn't be surprised, full of tasty things. I would see them occasionally come out when the lights got really dim at night. I had a third, a male, and both these females were always berried. I haven't seen the male or it hasn't come out like these two. I am thinking maybe they are getting ready to molt but I'm not sure. They would hang around the floating breeder box or amazon leaves and constantly clean themselves. I haven't seen them eating or foraging. Their behavior has been different, that's for sure and starting to get me a little worried. My bamboo shrimp also lives in the anubias driftwood (the circulation pump blows over and through the anubias).
My tank is co2 injected fully planted, long established, 12 years or so. My parameters:
Ammonia 0
Nitrite 0
Nitrates 10-20
PH 6.9 after injection
GH 7
KH 6
Temperature: 76F (during cooler months), 77-78F (during warmer months).
Weekly water changes, about 30% to clean up organic debris and remove any excess fertilizers. I dry dose daily, a very light EI method.
