community Goldfish tank, going great
« on: December 09, 2011, 10:35:18 AM »

I moved up from a 10 gallon tank to a 75 gallon tank.  I have 2 fancy tailed goldfish.  I've had success with making it a community tank.  We have 9 silver tip tetras, 3 tiger barbs, 2 green cories, 2 algae eaters, 1 pleco, 3 blue goramis, 2 large snails, a loach and a catfish.  We also  have a few plants.  Been doing this since August, its worked out great so far.  We did lose 2 tiger barbs (orginally had 5)because the tiger barbs have to have that pecking order, aggressive. My goldfish are about half grown, maybe a little more...about 4 inches, not including the tail. Although it is not recommended to have a tank set up such as mine... its working out just fine.  I have a filter for a 100 gallon tank hooked on it, fluval 450, and two airstones under castles and a 100 gallon pump that circulates and oxygenates the water good.  The pH stays at 8.2.  No water condition problems. I run the filter about once a day, for at least a half hour.  We live in a rural area, so I use well water. I don't have to treat for chlorine. Also there are some natural wood pieces in the tank too... I just wrote this in case anyone out there is wondering if you can do a community tank with goldfish. I don't know about other kinds of goldfish, but its working out great for our two fancytails. They do pick at the gravel, and want to eat all the time...and as they get bigger, so does their mouth, it has been neat to see them grow and change colors from time to time. I do have large sized gravel, pebble sized, which has worked just fine to keep them from rearranging things. I will have to get a second heater though, as the fluval 300 watt doesn't seem to be enough...it gets stuck at like about 72-73F.  Its about 64F in our house. Anyway I just wrote this so other people who are looking for information on having a community tank with goldfish that it can work.  I think part of the trick is starting the goldfish early in a community tank, so that they get used to having other kinds of fish around. the other important basics of goldfish are having adequate filtering, aeration, and large enough gravel... these things are little more important for goldfish's needs....they are a bit messy, so they need extra filtering, they  need extra/strong aeration, and large gravel, so they don't choke... once you've got all that, caring for goldfish should be easy.  I've had several tanks, been an aquarium hobbiest a long time...just recently got back into it,  most of the aquarium products today, make it so much easier than it used to be... and thanks to my son, I now have experience with goldfish! Smiley I was leery for years to get them, never did.  Son really wanted some goldfish, so I was like okay I'll give it a try...its been great! Thanks for the input on the forum here, its been very helpful!

It sounds like a lovely tank!

How do the fish get on with the goldfish? As some of those fish you have there are known to nip the fins of fancy goldfish....
What type of catfish, loach, algae eater and pleco do you have? As you don't specify breeds and I'd be quite interested to hear which species you have  Smiley

But you really need to have the filters on 24/7, not half an hour a day.
You are aware of goldfish needing extra filtration, but that filtration is useless, if it's not on all the time to keep the water clean for them.
In fact in any tank, for the filter to be useful, it needs to be on all the time, so I'm not sure where you got the idea of only having it on for half an hour a day?

I agree with Skwishee.  Running the filter once a day is useless, actually. No offense, but do you think the rivers are flowing only half an hour every day and then stop? Goldfish are river fish and they need moving water. all of your fish do! If the water surface isn't moving, your fish will suffocate. Always have the filter on 24/7, ALWAYS. You can turn it off while doing some maintenance and cleaning the filter (in old tank water!!).
However, you could skip the air stone, it's actually harmful for the goldfish if they unintentionally swallow air bubbles from the bubbler.

I had (and to some extent still have) a community tank with goldfish. And considering the fish you chose, you didn't really do any research on the other fishes' needs. The barbs and tetras want soft water, and the goldfish want hard water. You'll have to try and soften up your water's general hardness a little bit for all the fish to thrive. The pH is a little high for the barbs and tetras.
The tropicals you have there also want a lot warmer water! Goldfish can enjoy temperatures up to the high 70s, but the tropicals need this temperature. Maybe your heater is too small as it can't heat the water properly?

Of course goldfish are good fish to have in community tanks, very peaceful and kind Smiley But you need to pick the tank mates so that they will be comfortable with the needs of the goldfish too! As you know, goldfish are coldwater fish, they want alkaline and hard water, whilst tetras and other small fish want soft and acidic water. Another problem is the size of the other fish. The goldfish will eat anything that will fit in their mouth, not because they're mean, but they just can't help it Sad

How often are you doing maintenance? How much water do you take out? Has the tank cycled?

I was gonna say something about the filter yesterday after reading this but could not find the words to say it with sensitivity (havin a brain fade day), I knew the goldfish gang would pick it up, well done Skwishee and Nossie... one thing I think jeffreynnefty should do ASAP is check the Ammonia and Nitrates levels, with the filter only running half hour a day, it would have to be way out of whack. And jeffreynnefty, please dont be offended, were only trying to help you avoid disaster.
cheers all > Ron

hehe, noticed everyone had an edit...

(I edited because I was reading some parts again and noticed I needed to add a few things xD)

A big water change and gravel vacuuming would be in order, most likely Smiley

Ah, but of course! We had a few members being banned from posting for a while after asking questions or giving some constructive criticism about how the forum would be run. It's better not to ask, really... Tongue
And let's switch topic here quickly now Grin
