Have i got too many fish ?

[Reconmasterxx]

Hi, I've been in the hobby for about 4 months now, I have a 120 litre tank with internal filtration standard that came with the tank, which some plants I currently have 10 Cochu’s blue tetras, 8 cardinal tetras, 6 penguin tetras, 6 rummy nose tetras, 1 dawaf honey goruami, 1 dawaf bristle nose pleco, 1 black emperor tetra and 2 Armando shrimp. Thanks for any advise

120 liters = 31 US gallons

Err yeah a little heavy stocked for up top, id opt to move everyone up to a 55g or get a second 30g+ and move 2 of the schools to that..

I would agree that it is overstocked. There is a rule of thumb to have 1 inch of fish to a gallon of water (which I do not recommend following), personally, I go about an inch of fish every 2 or 3 gallons.

If these fish are full-grown, and even if they are not it's a little too much. You can get a bigger tank for all these guys or another mid-size for some of them to move to.

I agree with the other members, you are over stocked. I would suggest the 55 gallon tank for the tetras they need the room to swim. I have a 55 gallon tetra tanks with several shoals of tetras and they make use of the entire tank swimming.

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).

What is the ammonia and nitrite levels?
How often do you do water changes?
What does the nitrate level go up to between water changes?
How often and what do you feed them?

------------------------
Emperor tetras need to be kept in groups of at least 6 (preferably 10) or more.

Bristlenose catfish need driftwood and algae to help their digestion. Make sure you have some driftwood in the tank, and if there is no algae on the glass, increase the lighting period by an hour a day and see if you get some algae growing. If you don't get algae after a week, increase the light by another hour and see how the algae grows.
