Stocking Fluval Flex 123l

[Dsteel18]

Have recently purchased the fluval flex 123l and I'm currently thinking of purchasing around 10/12 lamb chop rasboras and 2 dwarf gourami's. The tank will be planted and was just wondering for some other stocking suggestions that will complement these fish, thanks

What are the tank dimensions (length x width x height)?

What is the GH (general hardness), KH (carbonate hardness) and pH of your water supply?
This information can usually be obtained from your water supply company's website or by telephoning them. If they can't help you, take a glass full of tap water to the local pet shop and get them to test it for you. Write the results down (in numbers) when they do the tests. And ask them what the results are in (eg: ppm, dGH, or something else).

----------------
Dwarf gouramis (Colisa lalia/ Trichogaster lalius) and all their colour forms are regularly infected with the Iridovirus and or TB, neither of which can be treated. These fish should be avoided until the Asian breeders get their act together and clean up their stock.

Thanks for the reply, the dimensions are 82x40x39cm and the ph is around 6.7/6.8 and was able to find out the water hardenss is around 28 ppm

You have a great many options with this tank and your very soft water. I agree with Colin on the dwarf gourami, but there are other gourami species. Honey Gourami are fairly common, and there are some other less common species though most are a bit smaller, if that matters; pygmy sparkling gourami, croaking gourami, etc. The Pearl Gourami is a larger possible, quite peaceful. The Trigonostigma espei (lambchop rasbora) are well suited to most of the peaceful gourami. The very similar T. hengeli is a bit more colourful with the almost irridescent copper blotch.

If you do decide on any gourami, they are sedate fish so must have less active tankmates, like the rasboras mentioned. There are some other rasbora species, including the dwarf Boraras red species like B. brigittae.

Finding suitable substrate fish is a bit trickier if you want to stay with the SE Asian geographical region, but one of the dwarf loach species might work. Or if not bothered by mixing continents, the Corydoras catfish. These are all shoaling species requiring a group.

i would recommend pearl gourami! They are awesome fish, if you get some they do better in a trio not singles.

Question....the width of 40cm. Can you tell me if that is taken at the base of the tank or is that including the bowed front? Yes there is a reason why I ask
I want to get this stand with a stand BUT I do not want the Fluval stand. The one I want to get is the APS aluminum stand which is just a hair over 15" wide. I don't even know if that extra half inch would make a difference or not.
