Hi bought a 2nd hand juwel vision 180 on sunday, it had been running for 2 yrs, kept their gravel, used filter sponges and bog wood and new water was added. I tested today and ph was 7, ammonia 0 and nitrite 0. Had 4 tetras in the tank that came with it but 2 died within 24 hrs of tank being setup, i think this could have been due to the stress of moving them 45 miles in the tank with a little water then filling with fresh. When do you think i can add a couple of new fish.

Well if the gravel was kept and filter media aswell then you can add fish any time know. Just pick compatible fish and remeber not to overstock.
I know I need to add slowly but how many fish could i put it a 180ltr tank, im thinking of the following
6 zebra danios
2 dwarf gouramis
6 rainbows
1 red tail black shark
6 corys
8 neons
1 bristlenose pleco
and possibly 1 or 2 other types in small numbers.
If you could give me that in gallons I could tell you.
going by the 1inch of fish per gallon rule that is almost overstocked as is. I wouldn't add anymore fish, that stock seems perfect! 
Anyone else think diffrently?

cheers for the info, my lfs recently told me i could keep 5 danios, 3 platys, 3 corys, 3 gold barbs, 3 mollies and 1 siamese fighter in a 5 gallon tank and as i started to add them realised it wasnt right so bought the bigger tank and just leaving the fighter and platys in the little tank.
lol that lfs isnt the greatest.

180 ltrs is about 55 US gallons.
As for the suggested stock, it doesn't sound excessive, though it depends a bit on the size of the rainbows (several different species). Only change I would make is I would pass on the RTBS- if he gets aggressive (as they do), the corys will have a hard time of it. Instead, I would up the numbers of those tetras you have to make a school of 6-8. I would also make sure the gouramis are a male and a female, rather than two males. And let there be a quiet corner with tall or floating plants for them to hide in in case the rough and tumble of your tank gets a bit much for them. Caves and bogwood at the bottom will keep the corys and the plec happy. Make sure the substrate is not sharp or very big gravel, as it can hurt the corys' barbels. If you only have two tetras left in the tank, there will only be a small proportion of bacteria, so fish need to be added slowly. Add a few at a time, then wait a week and check the water stats. If the tetras you have are neons, ideally neons should not be added at the beginning- on the other hand, I think there is a stress risk to your present ones if you start adding other fish and leave them feeling exposed in this big tank. So I think I would go against common advice and start with them anyway. Add another four, keep testing the water and let them settle in for a week. Then add the danios. Then the corys- in two lots- or the bristlenose. Leave the gouramis until last- they are sensitive and should only go in when the tank has been settled for several months. This also gives you the chance to observe the tank and think about whether it may be a bit active for dwarf gouramis, whether you might want to go for a tougher gourami.

Hi and 
Going back to your first post you say you had a 45 mile journey. The amount of time that the filter was not running you would have little if any bacteria on the sponges and the gravel.
Two small fish in a 180 litre tank are not going to make much ammonia so if you now have any bacteria it will be very very little. As dwarfgourami says your stocking idea's are not excessive but you will need to add your fish very slowly and keep a close eye on your water stats. Good luck and any more questions please come back and ask

The males are the brightly coloured ones. The females are almost silvery, with just a faint tracing of the pattern.
