disease fungus

So I have noticed this developing on the piece of mopani wood that I have had for about 6-7 years. This is the second time that I have had to deal with the issue. The first time I just scraped it off with an X-Acto knife, but it is back again. I am left wondering is this harmful or just...

My fish keep dieing in my 250 litter aquarium, it started off as cotton mouth, on one of my sword tails, then my guppys had white fungus on there body, I have been treating this tank for over 2 months now an nothing is working, water conditions are perfect, pics of 2 guppys that have it today...

I’ve had my Betta about a month now and today I spotted this white/grey stuff on his tail. Is this a sign of disease? Or has he just got something stuck on there? His behaviour has not changed, he is still swimming around, eating and coming to the front of his tank to be sociable. He has a...

Yesterday I bought two Platys from Pets at Home, and less than 24 hours later I’ve noticed this tiny, slightly raised bump below the mouth of one of them. I’ve attached a photo that shows it quite clearly. Please can anyone advise me on what this might be? I’ve already rang up Pets at Home and...

Hello, I have bought, only yesterday, 3 more bronze corydoras in the pet store to add to my 64L tropical tank and I have noticed one of them scratching on the sand. Is it something I should worry about? My water was tested yesterday and all the parameters were good. The tank is currently heated...

Hey, please help me out here. My BGK has a whitish layer over it's body and eyes. Attaching a picture. Please help me out.

If anyone has any ideas on what this may be it would be hugely appreciated. Please find pictures below. The red streaks were present when I purchased her, I thought it was part of her colouring as it was one streak by each gill but have now noticed a second streak on each side - again appearing...

Hi, this is my first post. I have a newish 125l tank which was cycled at the back end of last year. We added a new Betta to the tank last week (also in tank 10 Espe’s Rasboras and live plants). At first he appeared very happy and explored the tank all day. Over the last day or two we have...

So I've had a number of fish die from this now. They get these white fungal-like growths, batches, on their bodies/fins...I change the water regularly, so I thought it might be fungus, so I put in the fungal medicine in that made the whole tank green, but it didn't seem to work and now they're...
