Okay, my 14yr old daughter finally persuaded me to let her get some tropical fish. We set up the tank a few days ago, temperature ok, put the stuff in you're supposed to. Water has gone a bit cloudy so we're going to put the correct stuff in for that too (as you can tell we don't speak fishy language so plain english please, :-)).
My daughter only wants a few small fish. We don't want to overload the tank. We also don't want endangered species like seahorses (i love them) so some advice on that would be good.
A few colourful fish, maybe a couple of those things that stick to the side of the tank and can we have those cleaning shrimpy things?
I'm not taking the mickey, i don't know what anything is called so please bear with me. We are very responsible and caring pet owners so no need for anyone to worry.
We want advice on getting the right fish for the size of the tank.
Thank you for your help!
p.s. i'm sure i'll learn the language soon.
I'd recommend that you read the Cycling sticky before going any further. This will explain how to build up large enough colonies of bacteria to deal with the harmful waste which will be produced by the fish but doing so in a way that is safe for the fish. It can look a bit much to take in at first glance, so read it, re-read it and ask as many questions as you like.
As regards suitable colourful fish for a 42L, I'd recommend the smaller tetras (eg embers) or rasboras (eg mosquito). Most of these are commonly available, but it's worth checking out your local fish shop to see what they have in stock. The advice provided by shops can vary in quality so it's always worth double checking on here, especially if you're thinking of buying fish.
A 42L tank is a good size for shrimp, but I'll defer to someone with more experience of keeping them for actual advice.

welcome to the hobby...42L is a little bit on the small side, but don't worry.
as others said first see what your LFS (live fish shop...or something similar I think) can supply...then research and decide.
Unless you want a million (and no I'm not exagerating) fry (that is babies/young fish) don't go for guppies, mollies, platies or endlers, unless you decide to keep only males (in this case I'd suggest endlers as they're small, pretty and most peaceful) and maybe a small colony of RCS - red cherry shrimp, or other small shrimps which you might fancy.

this is the endler male, maximum size 2.5cm
Red cherry shrimp...Neocaridina denticulata sinensis (thats the latin name, which is used when referring to fish as some common names mean different fish in different locations/countries)
ps if you want to keep a mixed aquarium, be ready to have an extra tank for the fry and a place to sell them on - also you'll need more females than males, as they'll harass them...I'll stop now or I'll continue going on and on and on lol ... just ask what you want /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />
Just looking back over the original post, I'll add a couple of comments.
The cloudy water will clear in a couple of days, so there's no need to add anything. As Jim says, there's no need to add anything at this stage unless you want to boost the profits of the shop. Most of the "bacteria in a bottle" products are of dubious value, and some don't even contain the correct bacteria for the second stage of the cycle.
Secondly, the only fish that stick to the side of the tank which stay small enough for a 42L are Otocinclus spp. but they need larger tanks to provide them with a plentiful supply of food. Keeping the tank clean (whether algae on the glass or waste in the substrate) is best done by weekly cleans, which won't take long on a 42L. The shrimp will help by mopping up uneaten food and I'll add at this point that it is very easy to overfeed a small tank. All the food should be gone in 2-3 minutes.
