New tank setup advice #1
Hi, I am setting up a new freshwater tank.

I have a 180litre tank with a under cabinet filter.

I have started my my collection and Plan on introducing new fish every week.

My plan is to have something similar to the list below. I have done a lot of research but would appreciate the opinion of some experts.

So I currently have:
8 danios
3 bristle nose catfish

What I am thinking of getting depending on advice
6 harleighquins
6 swoardtails
Tetras but need to do research on which type don’t want fin nippers
Guppies
Possible shrimp allthough understand That a lot of things like these as a snack.
Would like a feature fish but nothing to big, from what I have read a Betta (fighter fish) should be fine with what I have as long as I don’t get any fin nippers and only one.
Other option is a dwarf gourami or both if they would be ok?

Any advice welcome and any other suggestions.

Thank you
James.

Re: New tank setup advice #2
Nice tank. I (and likely others) have some thoughts re your potential choices. I can't reply properly just now but, in the interim, can you let us know what your water hardness is in CaCO3 or German degrees hardness (as this will help work out which fish are compatible with your water); assuming you're UK-based, those figures ought to be available for your postcode from your water company website.

Re: New tank setup advice #3
Hi, thanks for the quick reply.

Just done a quick check and the results are in but not good.

The water supplied is HARD water.

Calcium carbonate(CaCO3): 269 ppm

Hope this helps to identify what would be good.

James.

Re: New tank setup advice #4
Your water is too hard for tetras as they are soft water fish; I suggest instead that you increase the shoal size of the danios and add a shoal of harlequins.

Betta splendens and dwarf gourami are also soft water fish so for "feature " fish you might consider one or a pair of pearl gourami (Trichopodus leerii).

The danios would do better in a cooler tank as they're not strictly a tropical fish, but you could set your heater to 24C as a compromise that would suit everyone.

Re: New tank setup advice #5
What type of danios do you have, out of interest?

If you're keen on tetras, then the x-ray tetra is a possible option for you - its requirements are 2-20 German degrees hardness (which equates up to 357 ppm / CaCO3), whereas harlequin rasboras' range is 18-215 ppm / CaCO3. The main issue might be whether the x-ray tetras would fin-nip the gourami - I've read mixed reviews as to whether they're fin-nippers. I wouldn't have trusted my own x-ray tetras with gourami - they tended to take a bite out my cories' tails when stalking them to avail of any extra food foraged up. If you wanted to take a chance on this combination, then best to ensure a large shoal with more females than males.

Guppies have a tendency to do the same with any fish with flowing fins or fancy parts on them, and male ones attempt to mate with such, so, although they suit your water hardness, may not be a wise combination with gourami.

Platies might be a viable option for you: https://www.fishkeeping.co.uk/modules/ ... sheet.php?caresheetID=202 and https://www.seriouslyfish.com/species/xiphophorus-maculatus/ ; https://www.seriouslyfish.com/species/xiphophorus-variatus/

As well as bettas being soft-water fish, it's very hit-and-miss as to whether they will tolerate any tankmates at all - so, between these two issues, not a risk worth taking. One option if you're keen on a betta might be to keep it on its own in a separate tank, using reverse-osmosis water. Pearl gourami are indeed a good option for the feature fish given that they can manage water 2-30 German degrees hardness.

Re: New tank setup advice #6
Thanks for all the advice it’s much appreciated.

I have just looked at the pearl gourami and have to say looks like a beautiful fish like the idea of having 2 of these and from reading seem very peaceful. Would you recommend a male and female or 2 females?

The danios I have are Zebra Danios I bought 4 that I put in the tank 6 days after setting it up and then added another 4 a few days later with the 3 bristlenose Plecos,

I am looking at getting my next addition at the weekend, I wonder if shrimp should be the next thing to get so they know 5ere way around the tank before others come in as they seem the most likely to be prey. What’s your thoughts. Also which shrimp type would be the best and most likely to survive I have seen the Amano and wood on my last visit to the aquatics.

Thanks for the advice, I never even considered the hardness of the water.

Thanks

Re: New tank setup advice #7
A male and a female would be best. If you want shrimps go for larger types - Amano size or bigger as smaller varieties will probably be eaten - even Amanos may possibly be attacked by your fish so try a couple before spending much on a bigger group.
