how many tropical fish and what type of fish can i fit in a 70 litre tank measuring 61 x 31 x 46 cm?

Answer 1

70 litres is a little more than 10 gallons, and once your factor in gravel, plants, rock, heater, etc, you have about 10 gallons to play with.
10 gallons isn't that big a tank, so your options are fairly limited. You can in two directions: tetra community, or livebearer community.

If you go with the former, you start with a school of 6-7 tetras, like neon tetras, glowlights, or even harlequin rasboras. Then you can get a centre piece fish, like a male betta, or a dwarf gourami.

Livebearers are mollies, swordtails, endlers, guppies and platies. Mollies and swordtails are too big for your tank, but you could get a variety of endlers, guppies and platies. Say, 3 of each (always get 1 male per 2 females - or ONLY females). Just know that these will produce lots of babies.

One last option would be a tank of female bettas (idea courtesy of Kylie ;) - female bettas are as colourful and varied as the males are, and you can actually keep them together withour them fighting. You could get a group of 3-5 female bettas of various colours for your tank.


Then you can throw in a mystery snail and voila, you're all set.



Oops, yup, you're right, that's more like 17.5 gallons which works out to 15 or 16 after you factor in gravel and other decor. My bad. Still, you can't double the fish I suggested, you can definitely get a couple more.

Answer 2

First you have to consider the type of fish you are going to add to the tank. Since you are running approximately 20 gallon, take into account water displacement of about 3-4 gallons you now have roughly a 16 gallon tank. Not much room. Remember the rule of thumb 1"=1 gallon doesn't always apply. This is a simple rule of thumb for novice fish keepers. Depending on the type of fish you are planning on getting. For example if you wish to have oscars, one would be pleanty with perhaps a snail. Mollies and guppies should be avoided since you will overpopulate the tank quickly, unless you keep all males. (Even all females brought home do not guarantee they are not already pregnant.)

Best advice, research or decide what kind of fish you want. Each fish requires different amounts of water to remain healthy.

Best of luck.

Answer 3

oops! 70 liters is almost 19 US gallons, so roughly double the number of fish above. Of course, that could allow you some additional options for some larger fish as well.

Answer 4

identification make it like the south american amazon rain wooded area, piranhas or oscars, with rocks and a super number of pretend plant life on the back of the tank yet open water on the front so u can see them

Answer 5

I like to use this general rule of thumb for community fish. 1 sq. in. of fish per 2.5 gallons for freshwater. And 1 sq. in. of fish per 5 gallons salt water. For aggressive fish, like Chiclids, cut the number by 1 quarter. So fresh water would be 1 sq in per 10 gal. and salt would be 1 sq in per 20 gal.

Good luck.

Answer 6

i would do a couple rainbow fish, a couple gouramies, a couple schools of rasboras, tetras, danios some cory cats and you are done. get stuff you like.
