Three of my CPD's have clamped back and dorsal fins. I have a handful of cherry shrimp and 11 CPD's in a somewhat heavily planted 10 gallon tank. Tank is fully cycled and been around for a long time.
Parameters are
Ammonia 0
Nitrites 0
Nitrates about 20
PH approx 7.4
Temp 73
KH 5
GH 8
Most of my CPD's look fantastic with beautiful flaring fins, colorful spots, and are growing nicely. I bought them all as juveniles (one batch about 2 months ago and one a month ago).There are 3 that remain very small and have clamped fins (from the most recent batch). One of them appears to have a very dim light colored line that goes around the tail, another one has a slight light discoloration on top of his head, and the third nothing but the common feature of clamped rear and dorsal fins.. Does anyone have any ideas? They seem to just kind of hang out in the top third of the aquarium, a bit lethargic, but still eating (albeit less than the other ones). They are definitely the smallest of the group. I haven't lost any yet, but starting to worry a bit.
I have attached a couple photos of the ones that don't look well.
Any help would be appreciated.
