Ever see Goldfish that lay on the bottom of the tank? If so, perhaps you can answer this goldfish owners question.

"We have a 75 gallon fresh water aquarium with 7 fish. The fancy goldfish have taken to laying on the bottom of the tank except when the light comes on. The water temp is fine and the fish seem to be okay once the light goes on. What could be causing this? We have had our fish for quite awhile and we don't want to lose them. Please let me know what may be causing this and what I can do to rectify this problem."

I’ve kept goldfish for years, and they’ve all displayed the behavior you’re describing. This is how they rest at night. Google goldfish sleep for more info. As long as your guys are healthy otherwise, I wouldn’t worry about it.

My four-year-old goldfish did this a lot. As long as he is resting in an upright position, not leaning on his side, he’s probably OK. The fact that he perks up when the light comes on indicates that it’s just resting. My goldfish, coincidentally, had a lot of personality. His tank was at the foot of my bed, and when he saw my feet move under the covers in the morning he’d go to the top and smack his mouth at the surface of the water to get attention. He wanted food!

my fancy goldfish, 2 males, both exibit this behaviour too. i don tknow whats going on with them, but they always get up and swim around when i move near the tank, and they eat fine and are healthy. as to the question about the while speckles, they are most likely white spot and you need to treat it asap. i always use salt in my tanks to treat white spot, rather than medications. just go and buy some aquarium salt, not marine salt, just aquarium salt for freshwater fish, and add it as teh directions say. give it a week and they will be gone.

my fish are always on the bottom and sometimes in mid water but they are fine. they eat well and come to the tank when i go near it or turn the lights on. but if you have white specks that is not good it can get sick and die so get some salt and if that doesn’t work use medications from the vet or pet store.

Good luck!

What does it mean when a fish occassionally swims on her back. The next thing you know she seems right as rain. It’s been going on for days. She also seems rather huge around the belly area and I think she may be full of eggs.

Okay I have a black moor that’s goin through the same thing. He was doing great for about 3 months. Until I introduced an algae eater ( the chinese algae eater not a pleco), the algae eater seems to be eating the slime coat off the black moor as well as my other two fancies! The black moor has lost a bit of his coloring do to the stress, and developed ich; also due to the stress and lack of slime coating. This morning I turned on the light and he was laying on the bottom, while the other fancies were swimming around. After a few minutes he began swimming normally for a short time then returned to his “lazy” state. What do I do?

As far as abnormalities in swimming ( upside down,floating, sideways, etc.). This ailment is very common in the “round” goldfish types, rather the long slender body types. This is due to pressure on the swim bladder or bubble bladder caused by expanding food in the fish’s stomach. As long as after a few hours it returns to normal, if this is the case, pre-soak any floating flakes or pellets you are feeding them and also incorporate vegetables into their diet. Frozen peas work best. Just. thaw the pea and shell it the squash the inside parts and drop a few in the tank(MAKE SURE THE PEAS ARE SODIUM FREE). If however, the disorder is not cleared up within a few hours of feeding time then the fish my have swim bladder disease in which case you should ask a local fish store (not petsmart or petco, an actual fish store) what can be done ASAP!

Anyways hope this helps!

I found that my gold fish was resting on the bottom of the tank all day..just rising for food. I found a resolution to the problem by buying it a mate, now they swim together happily.. ( or so I think so)
I seriously think that by having 2 gold fish instead of the one keeps both more alert and swimming, maybe it’s because they are competitive and looking for food. When they are alone it seems they have no competition and therefore enjoy the lazy life. :)
