hi guys as i have just setup my new planted tank today.. i got heteranthera zosterifolia, ambulia, water wisteria, amazon sword, echinodorus angustifolius and java moss. so when should i start adding fishes and shrimps? which fishes and shrimps should i add?

You do understand the nitrogen cycle and the need for a filter and to build up beneficial bacteria right? Almost all fish and especially shrimp will not tolerate an uncycled tank. Also depending on your stock, most fish will eat shrimp so they won't last long (unless you're getting nano fish and larger shrimp like amano).

This link should be helpful if you're not familiar with nitrogen cycle, it also includes an ammonia calculator if you decide to cycle using pure ammonia.

How big is the tank? What kind of filter are you using? What kind of fish are you considering?
If you have enough plants you can do a fish in cycling, starting with just a few and gradually adding more. The plants will take up ammonia produced by the fish waste.
Do You have a water testing kit?

i will buy the test kit today. i got a 20 gallon tank and ill only go for tetras and ottos. i have a tank top filter which cleans 100 gallons per hour.
is 36w cfl 6500k ok for my tank?

I like to fully plant a new tank, start any fertilizing and/or CO2 I'm going to use, and let the plants start to grow for a couple of weeks or maybe 10 days. Then add just a small number of the fish I plan to keep, perhaps 3-5 fish only, and let them live in the tank for another week or more. Then add a few more fish that I plan to keep, so I have half to 2/3 of the total fish load I plan to use. Wait another week or so, and add the rest of the fish. That has worked well for me for many new tank set-ups. The numbers of fish depend, of course, on the tank size. I last did this with my 65 gallon tank, using 5 fish to start, and ending up with about 20-25 total fish.

I have cardinal tetras and ottos in my tank, along with amano shrimp and several others. They get along fine. I would start with the tetras first and add the ottos last about a third at a time like Hoppy said. Patience.

thanks guys for your time and reply.. is 36w cfl 6500k ok for my tank?

The light should be ok for your low tech setup . Maybe float some of the wisteria at first. It should grow pretty fast up near the light .
I'd try a 9 hour photo period and regular dosing of ferts.
Definitely don't add any Otos until you've gradually fully stocked with other desired fish first. They need a mature tank and will need supplementary food even then.
Otos are not the best beginner fish.

ok gmh ill add ottos later. by the way i know that water will b cloudy till some days but my plants are stones are covered will laterite. so will it get clear by its own? i just have full laterite as substrate.
