I am looking at changing my tank, I currently have a fluval tank with external filter. The tank I am looking to replace with needs an internal filter, it's 30 litres, please could anyone recommend a good internal filter.
I have a very sick straight tail goldfish, been ill now for 10 days. Initially thought it is swim bladder so didn't feed him for 3days and then gave boiled peas as per info gained from Internet. I also do regular water changes and added some disease safe to tank as advised by local pet shop. Tank had 2 treatments....
He looks awful today and spends most of his time resting on the bottom, but this evening does seem to be gasping more. He has a darkened lump under his skin where I assume his intestines are and thought initially he was constipated. I am very worried about him - any advise would be greatly appreciated. Thanks
Not sure if you can help but I have a straight tail goldfish who is poorly :O(
He has been unwell for 10 days now, I initially thought it was swim bladder s0 didn't feed him for 3 days then introduced some skinned boils peas as per internet research. I also added some disease safe treatment to the water as advised by my local pet shop (I have done this twice as per instructions)
He is still not looking great, but is swimming around occasionally but spends most of his time resting on the bottom. He does look like he has a dark lump inside him which I thought was constipation but am getting increasingly worried for him. My other fish in the tank is fine.
