How much can i fit in my tank?

Question

My tank is only about 27L=

Gallons (british)=5.94
Gallons (US)=7.13
And i have 2 pink kissing gouramis in there about 5 to 7 cm tip of mouth to tip of the tail long.
I really wanted to have fry and heard that mollies, platys and guppies are really easy to breed and is almost impossibe not to have them breed.
Therefore i was thinking how many guppies, mollies or platys i can fit in there, with the kissing gouramis?
Would it be too overcrowded, if so what other fish will go well with my kissing gouramis(coz i heard they are quite aggresive)
that are small and easy to breed?
Mollys? Guppys? Platys?
Or maybe even an eel or somethingelse?
Please advice, suggest and answer soon!^^
Thank u!^^ = ] =)

Answer 1

Common Glass Aquarium Sizes



5.5 Gallon 16x8x10 (128 sq. in.)

10 Leader 20x10x12 (200 sq. in.)

10 Hexagon 14x12x18 (127 sq. in)

15 Gallon 24x12x12 (288 sq. in.)

20 High 24x12x16 (288 sq. in.)

20 Long 30x12x12 (360 sq. in.)

25 Gallon 24x12x20 (288 sq. in.)

29 Gallon 30x12x18 (360 sq. in.)

30 Gallon 36x12x16 (432 sq. in.)

30 Breeder 36x18x12 (648 sq. in.)

33 Long 48x13x12 (624 sq. in.)

37 Gallon 30x12x22 (360 sq. in.)

38 Gallon 36x12x20 (432 sq. in.)

40 Long 48x13x16 (624 sq. in.)

40 Breeder 36x18x16 (648 sq. in.)

45 Gallon 36x12x24 (360 sq. in.)

50 Gallon 36x18x18 (648 sq. in.)

55 Gallon 48x13x20 (624 sq. in.)

65 Gallon 36x18x24 (648 sq. in.)

Petite body fish

1” per gallon or 1” per 12 sq. in. of surface

For example 20 long has 360 sq. in. surface area

360/12=30

Can a 20 long support 30” of fish? Probably not.

A 20 high has only 288 sq. in. surface area

288/12=24

Can a 20 long support 20” of fish? Probably not.

A 25 is also 288 sq. in. surface area

288/12=24

Can a 25 support 24” of fish. Probably.

I like to average the two for a more accurate capacity.

For the 20 long, 30 by surface area, 20 by volume averages to 25”

Can a 20 long support 25” of fish? Probably.

For the 20 high, 24 by surface area, 20 by volume averages to 22”

Can a 20 high support 22” of fish? Probably.

Why does the 20 long support 3” more fish that the 20 high?

A larger surface area allows a greater oxygen exchange, which is as important as volume of water.

Large bodied fish, such as gold fish you need to double or even triple these numbers, i.e. 3 gallons per inch and 36 sq. in. of surface per 1” of fish.

This is not the only consideration for fish tanks. Types of fish will appreciate one type of tank over another. For example, fast swimmers like Zebra Danios, Pearl Danios and Blue Danios will do best in a tank that is at least 30” long. They would be better kept in a 20 long rather than a 25. Giant Danios would do best in a tank at least 48” long. They would be better kept in a 55 rather than a 65.

On the other hand, slow, tall bodied fish like Angel Fish and Discus will do best in a deep tank. They would be better kept in a 65 rather than a 55. They, like other cichlids also need a bit more than the 1” per gallon and/or 12 sq. in. surface.

Answer 2

The easiest way to calculate how many fish you can keep in an aquarium has to do with the total length of the fish and the surface area available. Each inch of fish requires 10 sq inches of surface area in general (each 2.5 cm of fish needs 62.5 sq cm).

Multiply the width & length of the aquarium in inches or cm and divide by 10 to get the total number of fish units you can put in the tank.

Understand, therefore, that a tank that is 12 inches water depth (30 cm) will hold just as many fish in general as if it was 39 inches deep (1 meter) b/c the surface area of that tank stayed the same.

Your tank probably has a surface area of 60-70 inches and can therefore hold 6-7 total inches of fish (15-20 cm). Your tank will hold 2 adult kissing gouramis only or up to 2 pair of mollies, guppies, platys. You will have to remove any babies due to overcrowding.

The caveat with the gourami is that they can breath air (anabantoid) and therefore, the full surface area rule does not apply in this case specifically. There are very few exceptions other than the gouramis and the Siamese fighting fish.

The aggression is only due to the small tank size. The more space you give the less chasing.

It is definitely easier to breed the live bearers (mollies, guppies, platys, swordtails) esp if there are no other fish chomping down on the babies and there is enough hiding places.

Answer 3

The common rule many people go by is 1 inch per 1 gallon. If you have a long tank.( tanks come made in long and tall sizes) you could add more than 1 inch for 1 gallon. but only like an inch more.Guppies are little fun fish. Mollies and platies are more fat.I would suggest get a trio of guppies. Guppies give lots of babies when the conditions are right. Live bearers like alkaline water so java ferns is the only good live plant to put in there, but live plant help the birth tank.The only other fish you could add in there would be 2 small Cory catfish. Big ones like to stress guppies. Guppies are easily breed, but raising them is another story.The only think i don't suggest platies and Mollies is that they get too big for 10 gallons and shorter.THey will need to school and they will be uncomfortable.

Answer 4

Hi most of the answers were good except the one who said don't listen to the rest of us. well anyways also take into account besides the 1 inch per gallon also take into account how much gravel and rocks and decorations you have in the tank to because they also take up water space so it would be a good idea to get a bigger tank it's good for the fish and in the long run you will have less problems example a fish dies in a small tank and you don't get to it right away a small tank will foul more quickly then a large one just because of the large volume of water also a larger tank will be good for the small fry also they can get away from the parents and other fish and hide in a small tank they have less space to get away

Answer 5

ma'am, your tank is too small for even one kissing gourami. I have 2 kssing gouramis and they are both 8" long. I would advise you to buy a 20 gallon tank (they are only about 30 dollars), return your kissing gouramis to the store, buy 6 guppies and 4 platies. You'll have fry in no time.



If you decide to keep the gouramis in there, they will fight the guppies in there to death.



Please, do not listen to the other answers. I come from a family of very experienced fish keepers.



And just so you know, a pleco fish grows to 24" long!!!!!

Answer 6

The general rule is that you should only have one inch of fish per gallon, but I don't think that gouramis are fat so you could probably squeeze a few more in. But I would really suggest getting a new aquarium. Having too many fish in one overcrowded aquarium would mean more diseases, stressed fish, and way more water changes.

Answer 7

For my idea, you'll could have/get your self a 2 longish skinny ribbons (only flow to a craft or textiles keep the position they inventory those large rolls of ribbon in about 40 different hues). If the tank is black, be sure for an exquisite colour, like fluoro orange, eco-friendly, or pink. Even white or cobalt blue will be effective. If the tank is one colour, be sure for a contrasting colour (eg, orange tank = remarkable pink ribbons, pink tank = remarkable eco-friendly ribbons). If it fairly is multicoloured, then it is your decision! ok, now for what you want to do. you want to tie it in a tiny knot at your shoulders, yet what i imagine of will be a cuter-searching idea will be to get someone (a determine, chum or in accordance to probability a sibling) to pull the the slack mutually so it matches, and then you've a loop at your shoulders. rather of tying this loop correct right into a contact knot, carry the loop mutually on the end, and characteristic your determine/chum/sibling tie one ribbon round it, in a knot, and then in a bow. If it fairly is notwithstanding too lengthy, trim the ends of the ribbon yet no longer too a lot, in any diverse case it is going to come undone. Then do the similar with the diverse strap. i fairly tried this with a smooth blue spaghetti-strap dress I had. The straps were too lengthy, notwithstanding the dress in any diverse case equipped thoroughly. It worked out fairly suited for me, so i'm hoping it fairly works for you! And there you've it! Shorter straps! it fairly is ordinary, amazing and a lot less severe priced! choose this facilitates!

Answer 8

The formula, on average, is 5 gallons per fish. I believe using U.S. measurements. I'd just leave it at the 2 fish and maybe an algae eater or a pleco just to keep the tank clean. Have fun with the tank! Eventually, get a bigger one.

Answer 9

The rule is one inch of fish per gallon of water. Keep in mind the size they will be when full-grown. Check out these sites. I tried to find one that gave you the inches for various types of fish (I saw it one other time) but couldn't find it.

Answer 10

You can fit a lot less than what the "man at the fish store" tells you you can...
