What kind and how many tetras IYO would go well in my tank? It's 40L/10 Gal.
Ember tetra Pygmy cory White cloud mountain minnow Honey gourami Sparkling gourami Betta (I know most of those aren't tetras)
There aren't many tetra species that should be in a 10g, they're too active and some can actually get pretty big (3in). How about ember tetras, a school of 8, as FallenOwl suggested?
I love the look of the ember tetras and also the corys! I was possibly even thinking guppies or endlers
I second ember tetras, endlers and sparkling gourami as great choices for that tank size. I'd do 1 sparkling gourami and 8-10 embers or endlers or even like 7 embers with 3-4 male endlers, they are both peaceful. Perhaps plus a snail or two and a handful of shrimp.
How about 7 embers and 3 endlers and maybe 2/3 ghost or amino shrimp?
Sorry to say but Pygmy corys aren't suitable for a 10 gallon, they need to be kept in groups. Although they're small they need more space as they spend quite a lot of the time swimming in the mid level unlike their larger cousins. Another option for you to consider would be celestial pearl danios.
I have 5 Ember Tetras in my 5 gallon shrimp. I have about 6 adult and 30 babies of different ages. The ET are very shy
This would be a lovely stock IMO. I would go with that- it would look so colourful and pretty!
In addition to the pygmies being inappopriate, WCMM and honey gouramis are too. Check out this (long) list of stocking options for a 10 gal: https://www.fishlore.com/fishforum/aquarium-stocking-questions/207629-stocking-list-10-gallons.html
Agreed, how about the smaller species of danio rerio? like CPDs or emerald dwarf's?
CPDs or emerald dwarf rasbora aren't smaller species of Danio rerio. Danio is a genus and rerio is the species name. CPDs and emerald dwarf rasbora are in different genera than Danios.
Thanks for correcting me I thought they were in the same genus, turns out I was wrong...
Thanks for your input every one so far I'm looking at endlers and ember tetras. With endlers, do you need to get all males/all females? I'm quite concerned about having lots of babies swimming around!
All male, if you get all females, you have the chance of her already carrying babies. If you plan on getting both, you stock should be something like 3-4x Endlers 6-7x Ember tetra With this stock you could also get- 2-3x Amano,cherry, or ghost shrimp 1-2x Nerite or mystery snails
Ok I'll look to get all males I don't think either of my local stores sell ember tetras any other tetras that would be suitable? I love Glowlight tetras but unsure whether they would suit my tank size.
Look at the list I linked in post #10. There's a whole list of fish suitable for your tank size. Glowlights will not work.
In substitute for the ember tetras you could do 3-5 sparkling gourami OR 3-4 African dwarf frogs OR 5-7 Emerald dwarf rasbora (as Five 97 suggested)
Since your lfs doesn't carry Embers, how about a large school of ruby tetras?
I'll probably look for either green neons OR emerald dwarf rasbora. I think they'd both look gorgeous against the black substrate
