How many fish can fit in a 70 litres?
I have a 70 litre aquarium and I want to move 6 guppies, 1 dwarf blue gourami and 6+ neon tetras in so far the stocking already is 4 swordtails 3 harlequin rasboras (I know I need more I am planning that already) and 1 bristlenose catfish, I want to move to make space for some angelfish in my 140 litre.
I know all my fish get along after a blackout ad to move them into my 70 litre (there all still in there after I am done treating a few illnesses I will move any necessary fish back to my 140 litre)
I don't think you would be able to do 3 schools, along with guppies, a place, and a gourami in a 20 gallon, that would be pretty overstocked. I would get rid of the guppies, and one of the schools, and increase the sizes of the remaining schools. I think if your pleco isn't interested in attaching to other fish, you may be able to keep him/her with the angel, but keep a close eye.
I could move the biggest sized fish school to the 140 litre with the future angels and see if they get eaten or not, and I could the swordtails to the 140 as well as they are much larger and unlikely to get eaten
What are the dimensions of these tanks?
A 20 Gallon can hold 1 Small school, 1-2 Centerpiece fish and some bottom feeders, for example(20 Long)
2 Croaking Gourami or 1 DG
12 Harlequin or Lambchop Rasboras
12 Kuhli Loaches
1 Honey Gourami
6 Asian Stone Catfish
What's the dimensions of the 70 and 140 liter tanks?
49 long 19 wide and 38 deep for 70 litre
82 long 35 wide and 42 deep for 140 litre
Assuming these dimensions are in cm, the small tank is actually about 35 litres (9g), not 70 litres. The only thing I'd put in this tank are the 6 guppies.
The larger tank is 120 litres (about 30g) so you're already overstocked with the swordtails, gourami, pleco, neons and rasboras.
