Re: Angel Fish - fungus on spine, gasping for air - how to treat it?
Hi. The fungus on your angelfish might be caused by stressful or poor water quality conditions. Or open sores and wounds can sometimes attract fungus. If it's like a white cottony growth on your angelfish then it's a mark of a fungal infection. Do an immediate 20 to 30 percent water change. The best recommendation is to use a general fungal treatment available from the local fish store. If only one fish is affected, isolate that fish in a quarantine tank for treatment.
Re: Rosy Barb loosing colour and inactive, other one is healthy
If she's eating just fine and you didn't notice other symptoms aside from losing her colour, I think she's doing okay and you have nothing to worry about. She just needs bigger tank though, as barbs are very lively and active. Try to observe if she has a bloated stomach or any other symptoms
