Ok my daughters wee goldfish is sick, last week we lost our blackmoor, entirely due to my son trying to catch it to show a wee friend while I was outside.
However since then for the past couple of days I have noticed our fantail hanging out at the top of the tank, (I know, not good).
Have checked the water and the ph was slightly high, so I have vaccuumed and done a partial water change, and now goldie is swimming around no worries, however he now has what appears to be a blister type growth near his gill and redness all aorund the gill as well.
His food was recently changed but have noticed no problems with his eating or toileting??
ANY IDEAS??
Kids would be shattered to lose another
