but thanks

could i ask someone for more advice?
what if i were to get rid of the glass catfish someone on another forum said 45 litres is too small for them :( and the ember tetra, shoal the neons in 5 or 6 keep the swordtail. how would that be? and then what other NON shoaling fish could i add in for variety?

i accept i made mistakes here. i researched so much about everything! everything except shoaling! i didnt even think about it
but thanks all for your help so far

so if i had a small shoal of neons and a female swordtail, what else could i add in eventually? some exciting fish NON shoaling fish perhaps quite strange ones. i'd love a lot of variety

the dwarf gourami doesnt sound a good choice, it says can become aggressive to bright coloured fish and i will have neons and the swordtail is bright orange...

what other choices could there be?

you're quite limited by the size of your tank about fish you can keep unfortunately. i think small gouramis (dwarf or honey) can be kept with small tetras but maybe someone else can confirm this?

take your time with any decision anyway. i took 3 months of reading forums before i got my tank!

Hi Josh and welcome to Tropical Fish Keeping forum.

Well, I've read through this thread, and I'd like to offer some general advice on the problems I see.

We are all limited by our aquarium size as to what fish we can keep. Fish are living creatures that have certain requirements, and each species can be similar or different in this. But if these requirements are not met, the fish will be under stress and stress causes health problems; it wears down the immune system quickly, causing the fish to be susceptible to all sorts of issues it would otherwise not have. So it is very important to know what the fish you "want" need, and be able to provide that, or look at other fish.

A small tank like yours is going to limit the type of fish you can have, and then the number. As you have already learned in this thread, angels, gourami, glass catfish are not possible. That leaves you with small fish, which are usually going to be shoaling fish; this means they must be in a group or they will not be healthy--or happy, and the two are related with fish.

Ember tetra need a group of 6 or more. That is a perfect fish for a planted 45 litre aquarium. But, what are your water parameters (hardness, pH)? Ember tetra are wild caught fish and they need soft and slightly acidic water. A swordtail is the opposite, it needs harder basic (alkaline) water. You should not mix the two, as one is going to be fine and the other not, which means more stress and sick fish. It is better to have a successful aquarium than one where you have fish regularly diseased and dying, that is very frustrating.

Neons also need a group of 6, and six neons in a 45 litre tank is getting full. A group of 6 neons and 6 embers would work, with maybe 3 Corydoras catfish for the bottom. That's it. But this means your water has to be appropriate.

If you want more fish, they will have to be small fish; but there are several possibilities. The Embers, one of the dwarf rasbora fish like Boraras brigittae, the dwarf cory species like Corydoras pygmaeus, a group of pygmy sparkling gourami, scarlet badis, ...there are quite a few, these are all shoaling fish, checkout the profiles on these and see what you think. But again, these are all requiring slightly acidic water to slightly basic.

Hope this helps a bit.

yes yes thank you, i will get a small shoal for the neons. and the glass catfish i would really like to keep, it seems fine with the others. someone said if i just get a partner it would be fine? unfortunately i already have the sword so unless there is anyone near me, i am in warwickshire on the border near leicestshire and northamptonshire, and would like the sword i will just have to keep it and see how it goes. im going to just relax a bit i think and monitor the fish. i should point out that i am an animal rght activist so no need to worry about the welfare of fish or any other animals with me! i did so much research, jsut didnt think about shoaling and non shoaling! i will also look into getting a small bottom feeder fish too, such as the ones you suggested. i am also interested in the possiblity now of a micro crab? what do you think?

so my stocking could be (once complete over a period of time):

5 neon tetras
1 micro crab
1 female swordtail
2 glass catfish
1 bottom feeder fish (such as the ones you suggested, maybe two if they require a partner)

now what are the main issues here? (hopefully none!)

and also it was recent that i added these fish i have so when should i add the next ones? i intend on adding the other neons for shoaling. should i add all four in one go?

i will let you know i have been on many forums asking the same things, and this has been the most helpful! thanks all!
