Neon Cory

**Sunshine** · 04-28-2010, 09:41 PM

I'm in the process of cycling a freshwater tank for my grandson. A 46 gal bow front. He wants those neon cory to be the first fish in there. He also wants brown striped barbs and zebras. Will all those fish be OK together ?

I would not start with corys they need to go in when the tank is established and plenty of detritus to eat off the bottom. I would also not get the barbs they are extremely aggressive and will kill everything in the tank including themselves. Zebras are Ok that is what I would use to cycle.

After the zebras, what would be OK to get until there is enough detritus for the corys ? He wants small fish so he can have more of them. Are the red tetras alright to put in there ? How long should he wait to get the corys ? I used 2 huge pond fish to cycle it. It's been 2 weeks, ammonia and nitrates haven't come down to 0 yet.

are the pond fish still in there. if so your ammonia is always going to be a little high what kind of filtration you running. there alot of different really hardy I always cycled my tanks with white clouds. If your looking for a really pretty small fish have you looked into cardnial tetras they are really pretty and are a little more hardy then the neons

Yeah, since you are using pond fish to cycle it, the ammonia will probably not come down. Those are really dirty fish and give off a lot of ammonia, it will most likely always have ammonia and nitrate. I would recommend taking those fish out and doing a really big water change, add a high quality bacteria, add a little fish food to feed the bacteria and initiate the nitrogen cycle, wait about three days and then add the zebras. Using this method generally cycles out in about a week. Add the groups of fish slowly, like a shoal a week, this gives the bacteria time to catch-up to the bio-load. The pond fish are going to condition the water to suit their needs, their needs are different than tropical fish. They are cold water fish that require a little higher ph and the fish you are wanting like a lower ph and higher temp. The red tetras (serpae) are generally hardy enough to cycle the tank as well. Not to be such a downer, but you will probably find the zebras to be a problem as well. They are surface dwellers, need to be kept in large groups, and are very fast and "boisterous". They usually end up eating all the food before any of the other mid column or bottom dwellers get any. This in return makes the general populous think they need to throw in more food, then you end up with an end result of ammonia and nitrate. A vicious cycle....If you would like I could show you some really sharp fish that go well together and could still keep the corys with them. A good idea when it comes to fish is to pick a body of water and keep only those creatures that exist together in their proper numbers. Make the set-up as close to their natural habitat as possible, and condition the water with natural trace elements to provide them with what they need to thrive. By doing this you will find that the entire tank will stay cleaner, your fish will have better color, live longer, and act more natural.

Well, yeah, this is a downer, he is 5 years old .. lol He wanted the corys, zebras, red tetras and the brown barbs. I can talk him out of the barbs. But, he really wanted the zebras and corys. Mainly just because of the way they look. I didn't know the corys were catfish till I looked them up. I was going to get the 3 zebras first wait 2 weeks than add 3 more of another kind. But, he won't be able to have 3 corys, will he ? I'll take the comets out.

Yeah, corys need to be kept in shoals, 1/5gal. is recommended, you will have a lot more activity out of them if kept this way....lol. If you want the zebras to survive long term in that size of a tank, you will need like 6-8+

**Sunshine** · 04-29-2010, 02:23 PM

Oh, so you're saying he needs more than 3 corys ? So, get 6 of each fish he wants ? Oh, and Jshroom, he has a Whisper filter that hangs on the back.

**Aquatic Specialists** · 04-29-2010, 02:39 PM

Yes, they are a schooling fish as well. I always suggest you get varied numbers of fish to off set the balance, like 6 zebras, 5 tetras, 9 of another, and so on.
