Hi! New goldfish oranda added to tank on Wednesday. No quarantine. Tank is cycled well established and normal parameters. Is this Ich or something else or both? I had these white bumps in ornadas’ heads before and in one occasion it turned to a horribles flesh eating disease. I think This guy...

Hi all. I hope I can get some advise. I have a 250L tank with previously 5 goldfish (3 fancies, 1 big oranda, 1 butterfly) and 4 danios. Water parameters and stable tank for 3 years; partial water change weekly 30ish% scheam water conditioning. Sand bottom, very little decoration plants...

Hello everyone! I know there are lots of posts about ich but I have never had one outbreak until now (I think). The quick question is: would praziquantel treat ich? I don’t have much ich ( 2 dots on each fish caudal fins) and I have been doing salt and water changes (I did not have a heater but...

So I bought the Phyton hose for my new 63 gallons tank .... I had heard of stories of goldfish loosing an eye due to this but I though “I will be careful!” I went to check my bathroom for a second, just in case all the water was overflowing or something and when I was back to supervise the tank...

Fin rot? Hi everyone! I think my goldfish has fin rot but may not be that. I had him for 6 months or so, lives in a 75 L -20gal with another small oranda and my water parameters are always very good (ammonia nitrites 0, nitrates 20ppm) with 70% water changes weekly. I noticed a hole in the end...

Hi everyone! I have an oranda that looses one to three scales every 2 weeks, they seem rip of his skin and he is not scratching against anything, there is nothing abrasive in the tank either and he does not have any other signs of disease. The scales grow back in 2 weeks or so. Is this normal? I...

Hi! I wonder if someone could help me to know what this is and if I should treat the aquarium. I have a 20 gal tank with 2 young fancy goldfish (around 4cm and 8cm long each of them now). They have been in the tank for 3 weeks now and the tank was fully cycled before I put them in. I usually do...

My first goldfish!

Hi guys! I have cycled my tank and now I am aiming to do water changes every 7 days but usually nitrates go over 20 by day 3 or 4. Can I keep it until nitrates reaches 40 or is this too bad?? I have a 20 galon tank with one plant and marimos and 2 small goldfish. Thank you!

Hi! I have a 20g tank cycling now for 5 weeks. My ammonia goes down very nicely from 4ppm to 0.25ppm in 24h. I have had nitrites up to 2-5ppm for 2 weeks now, but when I test for nitrites they are always 5 to 10ppm after 5 minutes... however if I leave the test tube it becomes red within a few...

Hi! I am half way through a fishless cycling (2 weeks now) and my ammonia gets down pretty quickly by now, from 4 to 1 in 24h. My nitrites are off scale (have been for the past 5 days) but no sign of nitrates yet. I did a 50% water change to keep things moving but nitrites are still off scale...

Hi! I am starting to cycle my 20 gal tank and yesterday added some ammonia for the first time but then realise it had surfactants on it. I did a water change but should I rinse the filter with tap water as much as possible to eliminate any traces of the surfactant? I had also added some bacteria...

Hi! I am starting my fishless cycling today and I bought some fluval cycling bacteria to add to start the cycle but I heard that it is a different type of bacteria and therefore better not to use it. I added 5ml before knowing this. I haven't added any ammonia yet. Would cause my cycle not to be...

Hi! I have a 20 gal tank and I am not sure if I should get 1 or 2 fancies. I worry that the tank would be quite stocked if I put 2, but I also worry that one fish only would feel lonely and bored. I was planning on one oranda + a moor. I have a fluval 106 canister filter and planing to do water...
