2 Julii Corydoras

[ron4sum1]

I recently got 2 Julii Cories from Paws for Thought yesterday. After bringing them home, I researched quite a few about them so that I'd know more about these marvellous species! The staff told me it is okay to keep 2 of them. As soon as I got home, some website states that it is important to keep 3-4, while some said 6+ is preferred. Now, I'm slightly worried because I can't afford to buy 2 more since my aquarium would get over populated. I have 5 Neon Tetras and 5 Harlequin Rasboras in 60L aquarium.

Any suggestion would be greatly appreciated !

Thanks!

I would say you could add 1 more, the other fish are mid water fish, corys stay on the bottom. The important thing is that you provide a nice smooth surface for them to dig around in. Ideally you would want a sand substrate, not gravel and especially not sharp gravel as they can cut themselves on it and get infections.

Alternatively save up for a bigger tank You can get some real bargains on eBay.

I think you could get away with 1 or 2 more

How long has the tank been set up?

The julli's are more than likely to be Trilineatus(three line corys),julli' are very hard to get hold of,and are often mis-sold has julli's has they look very similar,still a fab cory i have 15 of them

The tank's been set up for 2 weeks now. I suppose I could try getting 2 more since I could get 50p off ! I don't really know which julii mine is hehe! Do you have a picture or a link to show the differences. I've been googling with no luck

I presume your tank was cycled properly and is capable of sustaining your fish? I always worry when people say "its been setup for a few weeks now". Most people dont have a clue about cycling a filter. I trust you have a test kit to measure for ammonia / nitrite and nitrate? By all means tell me to clear off if you know about all this, im just concerned for your fish and wouldnt be adding any more until you know your take is cycled.

I don't have a test kit to measure chemical concentrations unfortunately .. I can't afford them unfortunately, so I just presumed that my tank's cycledish after 2 weeks and with my fish all alive! Hopefully, they can make it for longer until I could fund my aquarium better!

Your tank will not be cycled after 2 weeks,you have been lucky up until now in not losing any,dont add anymore cories atm,if you can't afford a test kit(which is a must)then take a sample of your water to the nearest lfs and ask them to test it,and write down what they say the readings are.

When your back from getting readings, jump into the Beginners Resource Centre and start reading up on the "Fish In Cycle".

You've got lots of water changes coming

Thanks! I've read a lot about cycling. We also covered that in Biology A2, so I'm quite okay with it. I just needed assurance to whether I could add 2 more Julii Cories. Yes, I do my water changes every week, about 30% of the total tank volume.

If you covered this in biology A2, why didnt you look towards the fishless cycle?

And weekly water changes could become daily 80% changes with fish in cycles......

What Mowbz said, start going 50% water changes every day if i were you. Your fish are probably dying very slowly at the moment, its not something you can monitor without a test kit. One day they will all go belly up. make sure you dechlorinate the tap water before you add it to the tank.

Cycling the tank without fish is what I primarily have done for a week, with the addition of de-chlorinator, nitrifying bacteria, and other accessories (filter/thermometer).

I don't understand If I did do the fishless cycle, do I still go 50% daily water changes? Because I thought when I added the nitrifying bacteria from the bottle, it would convert the ammonia to nitrites. So isn't replacing a lot of water would lead to more ammonia being present perhaps, since I wouldn't be able to know the possible concentration of ammonia. I've heard some incidents where certain location in the UK has certain ammonia concentration. I don't really want to risk it much!

you said you have fish, so how are you going to do a fishless cycle.

 

[ron4sum1]

you said you have fish, so how are you going to do a fishless cycle.

Yes, I do have fish now. Although before that, I cycled it for a week. After reading a couple of people who did fishless cycle, it lasts on average 4-7 days. Some people said you can add fish as soon as NH3 reading goes down below 4ppm, which lasted a couple of days. Now, if I left my tank for a week without any fish, I think it should be okay-ish. But I needed assurance I'm still new, and everything I'm doing is based on a couple readings and comparing the data so I could work out what I should do ! I'm really glad about this forum, since people can help me one on one

Edit: I don't think my fishless cycle worked out so much since I don't have a biological filter I have a crappy one that has carbon/zeolite catalysts. I'll be getting a fluval u2 in a couple of weeks time! So please survive fishies! D:

 

[Harlequins]

Firstly your filter wont cycle in a week...you having zeolite is the only thing thats stopping the fish being poisoned by deadly ammonia,but having this in your filter wont go through the biological cycle the filter needs to go through to support fish...
Once the zeolite reaches its limit it will probably leach back into the tank toxins which will harm the fish.

You do need to test you water - ammonia & nitrite daily with a liquid test kit and do daily waterchanges to keep your fish alive through the first few months at least.The ammonia & nitrite are both deadly to your fish and will lead to a nasty & untimely death if not kept on top of.
Waterchanges with dechlorinator are you best friend in a fish in cycle.

Dont add anymore fish until your readings are zero on a daily basis without the need of a w/c.
