Best Tank

Hi, I would like to get a 20-30 litre tank and keep shrimps, snails and micro crabs. I have been looking on the internet at tanks and reviews and cannot seem to find my ideal tank. I want a tank where parts are easy to obtain, my daughter who works in a pet shop recommended Jewel or Fluval as the best makes but could not find any small Jewel tanks. We had settled on the Fluvel edge but have read some bad reviews about fish being caught in the pump attachment. Can anyone please advise me on a good starter tank

Edit: Sue posted whilst I wrote this and it didn't actually post before I went out so sorry if it's now not relevant!

Hi I can tell you about the Fluval Edge but I can't really advise on whether it would be good in micro crabs - what kind of conditions do they need to thrive? Do they breathe air and need land?

I have an Edge and love it but it does have it's downsides. However if you're worried about the pump attachment don't be. I was concerned about that but I got myself a pre-filter (http://www.amazon.co.uk/Hagen-A1387-Fluval-Pre-Filter-Sponge/dp/B002LL32RY) and I've never had any problems. It does fall off during water changes so you just need to make sure that you've put it back on before you turn the tank back on again. I can't say whether that is an actual issue without a pre-filter though but for the sake of £3 I got one to be on the safe side!

The main downsides with the edge are that it has quite a small hole at the top which makes maintenance a little trickier. I manage fine with mine but it can be hard work at times, and aquascaping is hard with it!

It is a very nice tank but it needs to be filled to the top really to look it's best - hence my question about air breathing etc. I think it would look less good with a 'gap' at the top. I always get evaporation loss of water and it always annoys me in between water changes when I get the big air gaps at the top!
