I've talked to a few people that keep fish and some don't like goldfishes. I was told something about their large intestine and them frequenting the restroom alot. Do a lot of you have problems with goldies? If so, why?

If you have a proper size tank, good filtration, feed them a varied diet, and do your weekly 25 to 50% water changes, goldfish can be great aquarium fish.
They are very fun personable fish.

I have 2 tanks fully set up. the first one is fresh with 1 archer fish, 1 spotted green puffer, 1 jack Dempsey, 1 pleco and 2 shrimp the second is salt with a huma huma trigger, a porcupine puffer and a damsel... but my 75 gal tank I am cycling with 3 goldfish this tank has the cheapest fish but is the one I find myself sitting and staring at over my other 2. I think goldfish can be a wonderful fish to own and are fun to watch.

I have 10 goldfish myself, all doubletails marking my comeback since keeping singletails and several doubletails previously. Goldfish do not have stomach which is why they tend to poo heavily. Their GI tract connects from the gall bladder straight to the intestines. The only reason why a lot of fancy goldies suffer buoyancy issues is they are fed with the commercial food trash that contain a lot of starch in it including gluten meal, yeast, etc. Despite lack of enzymes to digest the food, they have bacteria lining in their GI tract that digest the starch but in return, produce gas. The gas produced, is the one that gets trapped in the GI tract and causes the fish to lose its swimming balance. This is corrected by incorporating acidophilus in the food recipe or make gel foods. Mazuri gel foods help a lot in this case and have the proper nutrition needed by the fish.

Twistermom is correct. What a lot of people are missing is enough space, filtration, maintenance and proper diet. Just because goldfish are hardy, it doesn't mean they can be used for cycling purposes, fishbowls and any other types of torturing environment. They can suffer badly like most other fish and are actually very prone to red streaks appearing on their fins and black smudges, both of which indicate ammonia and nitrite poisoning.

I might add that goldfish are very poor choice for feeders as these contain high levels of thiaminase. The thiaminase is responsible for blocking entry of necessary nutrients needed by the fish. This leads to high incidence of malnutrition on fish.

Adding to Lupin's post, Goldfish are bad feeders because they have serrated(sp?) spines that can hurt your fish. They are also usually very disease ridden due to their large numbers and small tanks at the pet store. When keeping commons as pets, though. I actually like the 15 cent feeders. They grow to have quite a personality. (And I mean GROW literally.) I once had a common from the fair that lived 15 years and grew to a VERY large size. We miss him dearly.

I have had goldfish for years. Currently I have one baby in a 10gal tank and it is just starting to get color. It is beautiful and has much personality. I am currently getting my 20 gal tank ready to move it in. With proper maintenance of the tank these fish give as much joy as any other.
