    Hi Guys,

    So my first post is to pick your lovely brains!

    Ok, I/my son has a new 35L tropical fish tank and I’m looking for ideas. I’ve looked around the web a little for some info and have come to the decision to have a bottom feeder and a number of smaller fish to accompany him. Tetras being the perfect size (1.5″ish) I was wondering if I could have 4/5 different spieces together rather than a shoal of one type. It doesn’t have to be Tetras, that’s just a size example, but if Tetras could be mixed it could be a good option. Please feel free to enlighten me to other spieces as I’m totally new to all this.

    Thanks in advance for any help…it’s much appreciated!

    The rule of thumb that is sometimes used for estimating how many fish you can keep in a tank is approximately 1cm of fish per 2 liter of water. In a 35 liter tank, that means about 17 cm of fish. If we use 2.5cm long Neon tetras for the basis, we can fit 7 of those in your tank. Of course, you could, in theory, have 2 of each of 3-4 different species, but this would, in my opinion, be a bad idea – the way I sometimes have described it is that you tile your kitchn by going to the tile shops and asking for as many samples of different colours as possible, and then put that on the wall – it’ll be red, blue, yellow, purple, white, off-white, black, flower-pattern, stone, and all sorts of other things. The same applies to mixing a bunch of different fish in a tank, and not having “enough” to make them look good and feel comfortable.

    So something like 5-7 of some small, shoaling, fish is probably your best bet.

    If your tank is doing really well, you have a GOOD filter, and keep up your water changes very well (and do them large), and you don’t have very sensitive fish, you can perhaps stretch the number of fish a little bit, say to about 10 fish. But if you go much over, you WILL have problems.

    Hi Mats,

    Thanks for the info…much appreciated! /blush.gif” style=”vertical-align:middle” emoid=”:blush:” border=”0″ alt=”blush.gif” /> I’m open to all spieces, so someone please feel free to throw in a few suggestions.

    Thanks again!

    Guppies are all one species, Poecilia reticulata, though some of the ornamental varieties may have been hybridised with some other poeciliid at some point in the past. You could keep a pair but in a small tank like yours the female would likely suffer from incessant harassment by the male. A better choice might be one of the ‘Endler’s’ livebearers – a relative of the guppy but smaller. You could perhaps add a quartet consisting of a male and three females but be warned both guppies and endlers breed like stink (they give birth to live young) and personally I wouldn’t recommend them unless you have the facilities to grow on heaps of fry.

    Similarly, the majority of tetras do best and look most effective in groups as this is how they occur naturally. I think a group of a very small, schooling fish eg. one of the Boraras, Microdevario or Axelrodia spp. would be ideal for your tank. These all stay tiny so you could have a group of 10-12 or so. Additional interest could perhaps be provided by invertebrates such as shrimp or snails.

    Hi Matt,

    Some great advice there…thank you!

    I’m really liking the look of the Boraras, they’ll give my little’un something really interesting to watch. Are they readily available to purchase and how many could I introduce to the tank at a time?

    You also mention shrimps…they easy to look after?

    Thanks again!

    Thanks again! Here’s a little beauty for small tanks.

    You may want to consider a couple of Otocinclus sp catfish for algae cleaning and Corydoras habrosus, pygmeaus or hastatus. They all stay tiny. The hastatus has been found in nature swimming with a couple of species of tetra which they share markings with.

    Thanks Nomad, some nice options there…I’m getting spoilt for choice! /thumbs_up.gif” style=”vertical-align:middle” emoid=”:thumbsup:” border=”0″ alt=”thumbs_up.gif” />

    Remember that the dwarf corydoras still need kept in small groups of six or more, which would take up most of the stocking room. Otocinclus would need fed specifically rather than being used to clean algae.

    I have, in separate tanks, mosquito rasboras and ember tetras. Both are very colourful, so should engage your toddler’s attention.

    I’m not an expert on shrimp but the smaller species such as cherry shrimp are easy to look after and would work well. Two or three would have no effect on your overall stocking.

    As regards getting the tank ready for fish, we have a guide to fishless cycling almost ready to go so I’ll post what we have so far as a guide, and please ask as many questions as you wish.

    Heh Daddyfish, welcome to SF!

    Eyespot Rasbora are perfect for little tanks like that – coupled with 4 or 5 amano or cherry shrimp and a few plants they make a great display.

    I had 5 in a 12 litre tank with some Crystal red shrimp:

    Sparkling Gouramis are another option. Or a betta splendens and some females. Or a small group of honey dwarf gouramis.

    Maybe ramshorn snails as scavengers?

    Another option, which is commonly available, small and pretty – and shoaling: Danio margaritatus – Galaxy rasbora in the shops. It reaches about 1.5-2cm (5/8″-3/4″) fully grown, so you could have a few of those with some of the other small fishes suggested.

    Three of any tetra is really too small a number for them to feel happy!

    Just wanna say thanks to Eyrie, Bluedave and Nomad (again)…great ideas guys.

    Bluedave: I’m loving the idea of shrimps, I really do think I’ll have a few…do they need anything special, housing and the like?

    Nomad: I love the look of the Betta and I’m sure the little’un would be fascinated, but don’t they grow a little big for my 35L tank?

    Eyrie: I really love the Ember Tetra. I really didn’t want plain old goldfish, but these little guys look great in orange! /thumbs_up.gif” style=”vertical-align:middle” emoid=”:thumbsup:” border=”0″ alt=”thumbs_up.gif” />

    Thanks MatsP, that is my fav so far…I love these little fellas, but I’m not sure the heavy planted tank is a goer being new to all this. I’m sticking with Java fern and Moss in the short term, which doesn’t seem at all suitable.

    35 litres is more than plenty for a betta splendens. Most breeders keep them in gallon jars. I am not a keen exponent of the small container approach as you don’t get to enjoy the true beauty and nature of these fish. They are great. The first fish I ever bred, actually. If you ever decide to keep them, make sure the current isn’t too strong as, with their large fin spread and bubblenesting habit, they aren’t keen on current.

    A slow airdriven sponge filter is great.

    Ok Nomad, so how many females could I have in my tank with the male, bearing in mind I would like a bottom feeder or two?
