I was told today its 10gallons.
Type in "35 litres in gallons" into Google, it will do the conversion for you: http

/www.google.com/search?q=35+litres+in+gallons
The result is "9.24602183 US gallons", which is 7.69892051 Imperial gallons.
I estimated down because a 35 litre aquarium will contain only about 25 litres of water after décor.
I dont 5 large fish? I have 3 very small guppys that im told dont get any bigger, a fighter fish and a snail. The tank looks empty
Yes you do: you have 3* 5 cm guppies, 1* 5 cm Betta, 1* 1" apple snail. Those are adult sizes and add up to approximately 5 medium sized fish in terms of bio-load (how much waste they produce). They will grow to those sizes with good care, so you need to plan ahead. If you treat them as the little fish that they are now, there will come a time in the future where you will either need to get rid of some of your fish or the fish will suffer.
I was told today that 35litres will fit 15-20 fish in along the line of Danios, Tetras, Guppys.
Zebra danios, which the person who told you are suitable probably meant, grow to a whooping 5 cm and are very active fish: they can clear a 4-5 ft tank from one side to the other in under 1 second. In a tank which is under 2 ft long, they will only have enough space to go around in circles. There are smaller danio species which are more suited to your tank, but they're less common. Danios and tetras are also schooling fish, I wrote a short explanation of what this means here, please do read it: http

/aquariumadventure.wordpress.com/2011/09/07/deciding-on-fish-numbers/ , but in short, schooling fish should not be kept in groups of smaller than 6 and should ideally be kept in groups of 10-15+.
Personally, I think guppies are too large for this tank as well, but they are a much better choice than a 5 cm danio or tetra.
Another question, how can you tell if a guppys pregnant?
If a female has been with males and there is nothing biologically wrong with her, she will be pregnant. Unfortunately, you would need more experience and to know the individual female well to be able to tell by looking.
No an aquarium shop with 44 years experience, i used to go as a child with my parents.
Which is also 44 years of experience on how to make most money. Also, what about individual employees? I do not know the hiring policy of the shop you visit, but it is not uncommon for those who know nothing about fishkeeping to be hired.
Parents have never had a problem with them and neither has anyone else to be honest so i trust them fully.
No offence, but that's like saying you don't want to learn. They have already not been honest with you, but how will you realise this if you don't question what they say? I am not saying that you should blindly believe what I say, but I am saying that you should seek other opinions.
Unless you give examples of the fish your parents had and how long they lived for and how they kept the fish in different environments to compare behaviour, "never had a problem" does not mean anything, unfortunately. I often see people come on here saying "when I was little, we never had a problem doing x" only to find out that the fish survived for 1/4 of their natural life span. Humanity's understanding of how to look after animals has changed in the last 44 years and will continue changing. I encourage you to learn about the changes.
And yes, rather than be victimised about my tank and fish, i will stick to someone with 44 years experience
I am sorry that you feel victimised, I am sure everyone on here only wants what is best for the fish in the long term and for you to not have any negative experiences in keeping the fish.
I would like to point out a few things though: collectively, we have more than 44 years of experience in fishkeeping. A lot more. We do not know who you actually are, where you are from, what your name is. We do not have access to your money and will never benefit from your choices when it comes to the fish you keep. Since we will never benefit from anything you do, what do you think our agenda is?
For me, it is that I do not like to see animals hurt, regardless of whether they are aquatic or have four legs and bark.
