Hi there,
I have recently setup an aqua one ar620T. I cycled it for 3 weeks doing 20% water changes once a week before adding any fish. Used stress coat and stress zyme each time I changed the water.There is a large piece of driftwood in it and some live plants in a gravel base. Just using the standard filters plus a 150 watt heater at 24 degrees C. On Sunday afternoon we added 10 Neon Tetras, and they seem fine, no deaths yet and behaving just like the ones we've looked at in the stores always do. However this evening I noticed one of them has a relatively large lump on its belly. I have read about Neon Tetra disease, but I am not sure if this is what the fish has?
Water Readings are PH 6.0 (not quite sure why its this low, tap water is 7.4 here) Ammonia 0.25ppm Nitrites 0ppm and Nitrates 0ppm.
Any help and advice would be much appreciated,
Thanks,
Trevor
