Are the shrimp swimming around like this?
If so it’s normal and nothing to worry about.
You mentioned finding a molt and that’s a sign that the water is good. As Slap stated, just try to relax and observe. As long as the rest of the critters are doing ok and then it is most likely just an issue with that one particular fish.
I took the time and read all of the threads of this 6 week duration post thus far. Do guppies age so much in 6 weeks, that they are now old? There has been a lot of changes and interactions going on, babies, etc. in only a 6 week period in a non-cycled tank ... I am now dizzy from reading this. Please let your tank cycle 100% before getting any more fish and please try to limit constantly changing things up. You are only dealing with a small 5 gallon ecosystem and small changes to a tank this size are very major. I am happy you are so excited about the hobby and please keep that spark.I think they're getting really old. When all fish are gone, I will get otocinclus and some sparkling gourami.
