Best fish to cycle an aquarium with,

So I have heard mixed thoughts about this from different people and wondering if anyone had suggestions. I was told never to do it with goldfish? I would love to use something that I plan on stocking the tank with so I don't have to move it to a separate tank after.

It is going to depend the size of your tank and what you ultimately want to keep in it.

Goldfish are not good for a number of reasons, mainly being that you have to find a home for them once the tank is cycled. They are also very very sensitive to water parameters and susceptible to diseases. Also they enjoy a temperature(under 70) that makes for slow bacteria growth(much faster at 80 or above). They are just not a hardy fish.

Zebra Danios are one of the most popular. My Platties are doing really well, they have a healthy apatite, they are energetic, and they have no behavior that suggests they are feeling stress or sickness(lethargy, rapid respiration, inflamed gills, ect).

I would also suggest getting some live plants and seachem prime to help with ammonia and nitrite levels. Check parameters often!

I've heard lamp eye/ red eye tetras (Moenkhausia sanctaefilomenae) are good to cycle with.

It is worth noting that you don't have to cycle with fish. A simple search of this forum for "fishless cycle" ought to bring you up to speed on that method.

I've cycled with White Cloud Mountain Minnows and Pristella Tetras, both of which are pretty hardy.

30g SE Asian Tank
15 Lambchop Rasbora
2 Gold White Cloud Minnows
3 Dwarf Chain Loaches
2 Powder Blue Dwarf Gourami

55g Amazon Tank
2 Wild Type Angels
1 Marble Angel
1 Black Angel
1 Koi Angel
2 Bolivian Rams
14 Pristella Tetra
10 Dwarf Pencilfish
2-3 Twig Catfish (to come)

Its gong to be a 30 gallon tank and the inhabitants are going to be:
Pair of German Blue Ram's M/F
School of 10 neon Tetras
School of 6 marbled hatchets
school of 8 fire tetras
school of 8 lemon tetras
school of 5 panda corys

I have had it up and running for about 2 weeks and the parameters are pretty much what I would expect. As for live plants I have a few java ferns and a bit of java moss. I will be moving some dwarf sag and Cabomba into the tank once I have time to harvest some of it. The only reason I ask is because I plan on getting alot of my fish/plants at my cities fish auction (Oktoberfish as they call it) and hope that it will be okay to stock by next sunday

I would put as many plants in it as you can that will help with the cycle and make it alot less stressful on the fish. Hopefully you can put lots of plants and that will make it kind of automatically cycle in a way because it will have enough plants to control the ammonia and stuff.

Kindest Regards,

Keeping fish its not a hobby it is a passion!

I have a 55 gallon, 40 gallon, 29 gallon, 20 gallon tank, 5 gallon , and a 2.5 gallon all with real plants.

I'd say zebra danios but i'd also like to say that your tank is to small for all the fish you intend to put inside of it.
Your water will be always dirty, fish will be stressed and you will not enjoy your tank.
But you can also ignore what i just said.
Also you will have problems keeping all fish happy as some like higher temps while others like lower temps.
27-30 for the rams and the neon tetras like 20-25 (in celsius).
There is no way you can keep both happy.(Same goes for the other fish).

I expect nothing. I fear no one. I am free.
Excuse my bad and rusty english but i did not have your luck to be born or to live in a country where the main language is english.
P.S I am not rude, i just hate stupidity and act accordingly.

I will definitly take your suggestions into consideration, for the overstocking i use aqadvisor it is wonderful and is very effective at telling stocking levels. I also am using a filter with 600gph and do weekly 40-50% water changes on all of my tanks so it shouldn't be to much more work. This tank will also end up being heavily planted once all of the plants grow in. I will look into the compatibility of the fish again i thought they were all good at a happy medium of 75-77

I have to agree with redknee that is to many fish. I know on the other thread I said it sounded good but now that I really look at the list I relize how many fish it is. And I hope you are not planning on trying to add all of them at once that would be a very bad idea because it would be way to much of a bioload at once. The rams are very delicate when it come to water parimeters. I would definatly wait on them and I would seriously consider possiably leaveing out one of the tetras. If your plants were full grown I would be more willing to add more than one type of fish at a time but with them still being on the small side I would only add one kind at a time.

Kindest Regards,

Yes they will be quarantined and added slowly so I don't overload it.
