Suitable?

Ok,but the cloud was a greeny colour

Personally, I would change gravel to sand if you are seriously considering keeping Corydoras. Of course, sand have to be smooth and not sharp either. Like playsand. They prefer sand . If that is not easy to do, I would add sand to 1/3~1/2 of the tank floor space.
Also, I noticed your ph is little too alkaline(7.5~8.0). 7 is neutural and 8 is 10 times alkaline than 7. And I know most of your fish exception of Guppy prefer the water to be acid side. And I know most of the Cory does, too. So I would lower the ph slowly to 7 or less and move the guppy if I were you.
And also I would add more of the tetras(neons and glowlights) preferably 6 or more of each since they are schooling fish that enjoy their own crowd. Of course, you can't add them right now since your water is not sound steable nor matured completely.
How long have it been since you set up the tank anyway?

Messing with the pH will do more harm them good, 7.5- 8 is ok for cories, they aren't too picky about the pH, most fish aren't and can adapt quite easily.

ConnorsBala- About the "bacteria in a bottle", don't use it. None of those products have been proven that they work and its just a waste of money, all you need to add is declorinator to your water. Also, I'm off topic here, but are you planning on rehoming the bala shark? They can grow to over a foot long (12") and need to be kept in groups so require a HUGE tank. As for the the cories, I personally think your gravel looks suitable for them, of course they would love sand much better but they will (should) do fine on your gravel. Try to get no less then 3 cories (of the same species) as they like company.

Yay,ill probarbly get 4 sterbas maybe;would they be alright with botia sidithimunkis/dwarf loaches? The tetras seem fine with that pH so ill just leave it be. I kept adding pH reductor for about 4 dcays when the pH was about 8.5 and now its down to 7.5,without adding any. Of course ill be getting some more tetras! But not just yet,alike the corys,i want to put all the fish from my 10 litre in there,and then ill buy some more

IM definetly going to get some as ive realised that my dwarf loaches barbels are fine,so the corys should be fine too

regardless of that, i must maintain that if that gravel is sharp, it will NOT do for corys. It WILL damage their barbles during their constant foraging for food. loaches only tend to come out at night and dont spend the majority of a 24 hour period digging in the substrate for food.

And you'll also get fed up of that icky gravel in no time.

Is you saying my gravels disguisting! lol

 

[halfbloodprincess]

Do you have a bala shark? That tank is way to small for them!!! But anyway, just stick to getting more loaches. They will be much happyer. Plus you wont be able to get any corys if you up the amount of loaches. And if you do have a bala then definatly rehome it ameadiatly!
