Suggestion For Aquarium

[linux44]

Hi All,
 
At the moment my aquarium is juwel trigon 190 and is a corner aquarium.
 
I am looking to replace it with something that is squre or rectagular shape. I have two goldies and one algea eater ( very small and they don't grow).
 
What are your suggestions for aquarium ?
 
I will be buying it 2nd hand on ebay .
 
I have seen rio and it looks ok(juwel rio 180)
 
how many liters of water do i need per each fish ?
 
I think it was 20 gallon for first one and 10 for each additional one thus 30 gallon or 120 liters.

i would say a 80 litres for the first goldfish and 10 + more for each fish if there fancies but if there common i would say at least 150 litres with 50+ for each fish as regulars are very streamlined .

well what well known brands do you recommand which are either square or rectangle?

fluval anything fluval its all rectangular and the best plug and play tanks ont he market the other option is to custom make it but that is often expensive and can be complicated interpret is vast amounts cheaper but will have a filter that is too small and low power lights that wont really good for growing many plants
