Hello I'm keeping 3 fantail goldfish in a 55 gallon aquarium with 4 sponge filters with a 300 gph filtration with a common pleco. The Pleco is about 3-4 inches long and the fantails are averaged at 2" long. I would feed the goldfish ~3 times a day. I have a HOB filter for 75 gallon aquariums in there too. Weekly water changes probably at 60-90% for pristine water. How much can I stock? I would like to get a few black moores and hopefully orandas. What do you think ..read more

Hello everyone I’m new here but I’m not that new to fish keeping I’ve been doing this since 2020. Not a long time but I keep realizing how much I just don’t know as a fish keeper! And this is one of those times! My fish is a gold fish (not fancy) he’s a feeder. I got him from a carnival by accident along with 5 other fish however he’s the only one left.

Hi All I have an established 45 gallon tank with 1 regular goldfish in it. I feed it floating pellets and make sure that it takes them all, no decomposing food. *Edit to note that I use Well Water, we are rural. I take water straight from the well, it does not go through the water softener. Since the end of Sept 2023, the fish would exhibit what looked like ammonia burns, stop eating, lie on the bottom of the tank. I would WC of ~8 gallons daily. Gradually the fish would look better, start... Ammonia Burns ..read more

My goldfish, Topaz, has developed these marks on his face. I immediately googled the problem and saw maybe ammonia poisoning so I checked the levels and it was nil for ammonia and ph is good. I did a 50% water change last night as well. I have had him for a couple of years and he does have a tankmate whom I have had about a year. His tankmate, Quartz, has no marks at all and even Topaz seems to be eating and swimming around just fine but I am wondering about these marks, obviously...

Hi, I’m in desperate need of some advice to treat my 7yo fancy goldfish. Below is a photo of him from 1 week ago, he looks much worse now as my pleco ate quite a bit of his tail. The infection has spread to the tail base or it could be from being attacked by the pleco. He used to have a massive tail. Onset March -treated with melafix and primafix and condition stabilized 4 weeks ago problem came back -treated with melafix and primafix initially with no results -tried aquarium salt +...

Good evening. My goldfish has developed a black spot and a little ring of sorts around his left eye. I am including pictures of both eyes for comparison. Water quality, such as ammonia and nitrates, is perfect and I do a half tank change of a 55g once a week. I use Seachem Prime and I added Freshwater Aquarium Salt when I noticed this. Nothing on his tankmate and no other spots or blackness on him. It almost looks like he has a black eye, maybe bruised it or banged off the glass. The eye...

Recently, I've been checking out a lot of content in the internet on the fishkeeping hobby, and got nostalgic over goldfish, so I'm planning to get a fresh beginner start in the hobby again. I've kept goldfish once, when I was little, 2 orandas, they died early on cause I overfed them. My original plan was to get a 55 gallon tank with a larger stocking list, the main plan was to make a community tank with two goldfish. But seeing that I live with my parents in a deceivingly small house, I... Will my 30ish gallon tank be overstocked? Planning on keeping 1 goldfish, 3 platies/variatus, and 1 ..read more
