I have a fluval 125 tank with 2 bolivian rams and 8 kuhli loach. The other day I saw one of the kuhlis and he looked a bit unfamiliar and was very skinny with whiteish/pale sides over the colouring. Looked a bit worn so I tried to feed him but he swam off so I was unsure if he was eating properly. Today I found what I think was the same loach dead... With no signs of illness or disease
I also noticed afterwards one of the bigger kuhlis (~2 inches) looking swollen/fat on the sides (very suddenly) and the gills were moving open and closed very quickly as well as staying pretty much in the same spot for a few hours now.
Whats going on? all the other kuhlis (that I can see..) are doing great, swimming around, sifting through sand etc. The water stats are 0 ammonia 0 nitrite and 10 nitrate.
I added them 11 days ago after completing a fishless cycle.
