Help answer the question about Diffuser Filter
Why do my feeder fish keep blowing bubbles in the top of the bowl?
I have two feeder fish and I have them in a goldfish bowl and they keep blowing bubbles. why? Now before you get on me let me plead my case, first I went to the local store and talked with the pet department before i bought them. I informed them that I wanted to get a fish for my seven year old. I asked them What did I need and was Prepared to by a tank and system I was also prepared to buy a more expensive fish as well. They told me because I was just starting out to just get two feeders and a bowl they are cheap ($.15 each) little maintenance would be required at the most change the water once a week , feed them once a day, and I asked questions like how much water, how long do the water need to sit, etc... They told me 48 hours use tap water or distilled water.I did everything required and bought the two fish ( they told me the fish would get lonely and wouldn't survive by itself) I have found to be not the case When I called a Pet store in another city, the person there told me that they would eventually drown in a year or so and to come in and buy a beta. and that they require even less maintenance. i did come to this... I feed the fish smaller amounts once in the morning and once in the night... I change the water 3 times a week I went to the store and bout a whole bunch of distilled Diffuser Filter water and let it sit out to stay room temperature, my water change is about 98% clean water and that's so they have a better chance- they seem to swim better and eat than they did when i was doing the 50-60%. I use a strainer and rinse the rocks and tiny plant that came with the bowl. I have a bare bowl that i have them in for a few hours while I clean their house. I am going to buy a 29/30 gallon tank tomorrow I even though I see they com with starer sets ( filters, nets , water diffusers, etc) I want to know what THEY REALLY NEED TO SURVIVE AND BE HEALTHY? Will that be a too small tank ? What extra supplies do i need? What do I really need to do to the tank and whats the proper waiting time before I can put them into the tank? When should I change the filters. And If the question comes into your head why didn't I give them away the answer is no one i have encountered has an acceptable tank( most people have a 10-20 gallon with 10-15 fish, they are looking at their size because they are small no one thinks they need more room) and the store told me I could bring the fish back dead. I am looking for good solid sound advice not criticism, not saying that opinions don't matter But i'm not the one giving the advice or own stores with large amounts of fish in 10 gallon tanks or that sells these damaging fish bowls with deceiving pictures of 1 or 2 fish in a bowl to have people thinking that its safe. I also came across something stating that a fish only grows the size of the tank its in and in something else stating that a while a fish outside stops growing the inside doesn't and that their organs cet compressed and eventually die, which is true? Now i want these fish to have good comfortable home (a house is what you live in a home is what you live in and where you want to remain) for these fish their lives are priceless and they are depending on us take care of them. I hope I have given enough details maybe too much.So now that have pleaded my case Its time for you to pass judgment and give me my advice please... Thanksp.s. sorry if I offend anyone. iwell what kind of water do l use which is better purified distilled plain tap. I didn't know about this site until i just came across it yesterday I'm not really a internet user. As for me not doing research I asked people who already have tanks for years and like l stated they have 10-20 gallon tanks with 10-15 fish and i was not basing that on what i seen in the store. I was going off the advice i got from the store l bought them from ( l went in 3 times before i bought the stuff) and the advice from the other pet store so i was trying to research and I was not given the right advice. lt's not my faylt they are giving out the wrong advice ,
