I recently completed a fishless cycle and added cardinal tetras, harlequin rasboras and one guppy to my 29 gallon planted tank. All seemed well for a few days but I came home to three dead Cardinals yesterday. The deaths were unexpected. The other fish seemed fine but I noticed last night one stopped schooling with the other five and hide out in plants. This morning, it was still off on it's own. I set up an extra 10 gallon and just caught the fish and plan to put it in the other tank to treat it but I don't know what to do.
The fish seems to have good color and doesn't have any visible thing wrong with it on the outside. However, it doesn't swim much it just hangs out by the bottom of the tank and was really easily caught. When I placed it in my transport container it "swam/floated" for awhile with it's head pointed toward the bottom.
I did have a pH swing two or three days ago but all seemed fine after that. I have sorted it out since then.
Tank parameters
Ammonia: between 0 and .25
Nitrites: 0
Nitrates: 10 ppm
pH 7.4
temp: 76 F
Tank size 29 gallon set up for about 5 weeks
Filtration: Aquaclear 70
6 cardinals, 1 guppy, 9 harlequin raspbora (all juveniles)
Water change: day before I got fish, has been less than a week (got them last Thursday, July 9)
I acclimated all fish over the course of an hour and half guppy and harlequin I used the floating bag and water exchange method. For cardinals I used the same method but in a bucket.
Nothing new to the tank: have lava rock and malaysian driftwood and plants in tank since beginning.
I feed NLS .5 mm pellets. I did feed some bloodworm 2 days ago but I soaked it in tank water for 15 mins before giving it to tank.
Any ideas what to do or how to treat it? I like the cardinals a lot and would hate to lose more
