Help Tiger And Rosy Barb

[jhf18]

Hi

I have set up a 60L globe fish tank, I have got 2 artifical plants and 1 real one. I completed a week of fishless cycling and my water came out ok just a little hard. I purchased yesterday 4 tiger barbs and 2 rosy barbs, they all seemed to get on fine yesterday swimming around the whole tank. The tiger barbs are small about 25mm and the rosy barbs are about 50mm. Today when i got up one of my tiger barbs was dead at the bottom of the tank and all the fish seem to be staying near the bottom and are not swimming round very much.

I dont know if something is wrong or not and if so what action i should take to correct it.

Any suggestions/advise?

Thanks

James

I dont really understand what they mean, its from a tetra test 5 in 1 strips

Also i have got my heater set up at 25deg C

Need ammonia reading plus test strips are not that accurate.
Take a sample of your water to the lfs and tell them to write the readings down for you.
How long did you climatise the fish for, and what was the ph of the store to your tank.
Barbs really need to be in a biigger tank 12 gallons is to small for them.
