Re: Tertras if water is hard? #41
Hi

The figures we use in fishkeeping are ppm of calcium carbonate or German degrees. Your water is very hard and the only tetra I can come up with that can cope with it is the X-Ray Tetra, Pristella maxillaris. Have a look here for more about them and some pictures: https://www.seriouslyfish.com/species/pristella-maxillaris/

Re: Tertras if water is hard? #42
Oh thank you. My water supplier gave me the hardness information when I put in my post code.
It says very hard, but also measurements which I don't understand the meaning of.
I have taken a screen shot of the information it gave me.
I have tried to attach the image to this message. Hope it works.

Re: Hi all bettas and guppies? #43
The more tanks the merrier. I started with one with a rescued pleco in it and now have 10

Re: Hi all bettas and guppies? #44
Thank you for the reply that leaves me slightly gutted as I want some guppies 😂 I made a mistake with the shop I first went as they told me alot of false information which I only found out when I decided to use a new fish store, might have to speak to the other half about getting another fish tank 😂

Re: Hi all bettas and guppies? #45
Unfortunately no. There are two reasons - firstly the betta will see the guppies as competition and attack them because of their colourful flowing tails and secondly, they require opposite parameters. Bettas need soft acidic water and guppies need hard alkaline conditions.

Hi all bettas and guppies? #46
Hi everyone I'm new to the hobby I have a 60 litre tall aquarium I currently have 6 neon tetras 2 rams and a male betta, I was wondering could I have guppies and a male betta in the same aquarium? Iv seen conflicting information everywhere about it so I thought I'd join a forum and ask 🙂 thank you for your time

Re: Tertras if water is hard? #47
I'm afraid the person in the shop wasn't telling the truth as tetras cannot breed in hard water. Any bred in the UK are bred in soft water - either RO or rainwater. Plus, that shop buys its fish in from wholesalers who source fish from foreign breeders and wild-caught, not local bred.

The first thing to do is to find out how hard your water actually is. You can find out from your supplier's web site. Look for a page on water quality in your area, input your postal code and you'll get a full report including hardness. You can then compare your hardness to the requirements of the fish on a site like this one, or https://seriouslyfish.com/knowledge-base/

Even if you can't keep neons or cardinals there are some tetras that can cope with harder water (depending on how hard). Pop back with your hardness level and we'll see if there are any that are suitable.

Tertras if water is hard? #48
When I had a fish tank in west Oxfordshire, England, we had neon tetras which were fine. I don't know what the water hardness is like in Oxfordshire though.
Now I live in North Wiltshire and setting up my own tank. I think the water is quite hard where I live as lime scale build up is quite a problem, as it often has to be removed from around the sink etc. I'm told water hardness is connected to the PH level.

As I haven't kept fish for quite a while, thought it's a good idea to watch youtube fish keeping videos to refresh my knowledge, and a video said you shouldn't keep neon or cardinal tetras in hard water. I assumed I should look for another type of fish more suited to hard water and forget about Neon or Cardinal tetras. Although while I was in Pets at Home in Swindon buying supplies to set up the tank, thought I would ask person who specialises in the fish, and she said, yes if the fish were taken from the Amazon soft acidic water, then they wouldn't last in a different type of water, but they have been bred and kept in Swindon water so used to it, they will do fine.

The video saying tetras should be kept in soft water was by a man in the USA, so maybe they're more likely to have fish from the Amazon?

What do people think on here? Should I still get Neon or Cardinal Tetras, or go for another type such as Platies more suited to hard water?

Re: Do you need a plant substrate? #49
I was confused myself, as when I had a fish tank with my ex husband we put the plants in the gravel and they did fine.
I have been recently trying to set up a new tank, and when chatting to a person at Pets at Home they told me if you want real plants you need a soil, so I was confused if I should have real plants when only having gravel.
Then I was told plants can do fine without the soil, for food and for looks, but they won't grow as much as if you use the soil.

I also have some moss balls, as they can just sit on top of the gravel.

Re: Guppies staying at surface #50
There are a few possibilities:
* the filter bacteria are struggling to catch up with processing the additional fishes' waste - for the next 6-8 weeks, do daily/twice-daily testing of ammonia, nitrates and nitrites with a liquid-based test kit, and if there is any presence of ammonia or nitrite, do additional/larger water changes as per https://www.fishkeeping.co.uk/articles ... ammonia-nitrite-spike.htm
[...or, the more likely explanations, if your water quality is still/currently showing 0 ammonia and 0 nitrite...]
* the tiger barbs are harassing the guppies (when you're not looking) - often, tiger barbs are best kept in a species-only tank, and the guppies' fancy tails may be too tempting for them to resist;
* what is your water hardness levels in CaCO3 or German degrees hardness? (Water/utility website ought to give the specific results or GH/KH tests.) If below the required range (143-536ppm/CaCO3), it may be that the guppies can't tolerate this.
