Hello

[FairyFin☆]

Maybe peacock gudgeons for the bottom half and halfbeaks for the surface. Or some of the smaller Pseudomugil rainbowfish (Pseudomugil getrudae).

I want a school of cardinal tetras

 

[Rocky998]

They seem like too much of a headache

Yah they can be really violent.

get a longer tank

If the tank was on its side, then it would be easier to stock

I want a school of cardinal tetras

But not in hard water

My municipal water:
GH= 290

But not in hard water

Can peacock gudgeons be in hard water like that? I thought there were reports of them ain harder waters but I'm unsure... Also you couldn't switch them from a softwater environment to a hard water one... They would be put into a shock

Not really. Their range is 5 to 10 dH (90 to 180 ppm) So 290 ppm is too high for peacock gudgeons as well as cardinals

Oh nooo...

Of course there are ways to reduce GH..........

 

[Rocky998]

We need hardwater options then...
And I'm not familiar with hard water fish so....

That's true. It just cost more money and it can be a bit tricky at times

The usual recommendations for hard water are the common livebearers, rainbowfish (a couple of species are soft water so it's advisable to check before buying) and for very hard water and a suitable tank Rift Lake cichlids.

Rainbow fish... Yes but isn't the tank a bit too small? (Footprint wise)

 

[Essjay]

There are some small rainbows in the genus Pseudomugil. Some come from hard water, some from very hard and some even from soft-ish water

But with a molly in the tank, they might be too small and be stressed by the larger fish.

But not in hard water

That's why I put mostly (3/4) "bottled" drinking

Oh nooo...

Dude, that's why I put in 3/4 bottled water that had multiple steps of RO, 1 micron filtration, deionized.....there's not much left in it. I'll get a master test kit when i get paid in about a week to see where everything is at, both in the tank, from the bottle filling station near my house, & from the next town that seems to have a lot better (tasting) water. My friends living there have Hillstreams breeding like bunnies & I make it in there at least once weekly & really don't mind hauling buckets for water changes to maintain parameters where I want them.

Sounds really good as long as your willing and able to pay for that for every water change
