They don't have the pain receptors which allow us to feel "pain" that is not to be confused with the receptors which allow us to feel contact ect. But that being said it is possible their nerves preform the role of both as some evidence suggests. So best to behave as if they do than think they...

No, no, no, either use an overdoes of Anaesthetic, or a sharp hard blow to the head followed by using a needle or pin through the brain are the only two ways I would recommend having to do this awful task. These are the way to cause the least amount of pain possible to the fish.

I have intake sponges on all of my tanks filters, even the small ones. It prevents a lot of gunk getting into the filter "box" it'self and I think if it's leaving less gunk in the filter there is more surface area for bacteria to grow. I don't really clean the filter media any less than I would...

I agree with the posts above, If you can re-home the fish currently in there, you can get a nice Betta for the tank.

Hi, If you can give us a list of your water parameters we can work to find some fish which are compatible for you. We are looking for Gh, Kh, Nitrates and ph of your water. Will/ does this have a heater? Does this tank have a filter? What plans do you have for the decorations of the tank...

Hi, How do you know it is turning off? If you are just watching the little light which many of them have, that's connected to a tiny thermostat in the heater which turns it off when you are at the desired temperature and will turn back on when it gets a bit colder. it stops the tank from over...

If we knew your water parameters we might be able to give you better suggestions temp. Gh Kh. Ph ect

Not entirely convinced, I'll have to have a look into it a bit more.

Yeah but my point is if the OP didn't know to off gas the water all of his readings will be affected by the inclusion of CO2? His past tap readings (which were not off gassed) were 7.2 this has risen to 8 (not off gassed) and has dropped when been left for a while to 7.8?

I am clearly misreading something then, you are suggesting that dissolved CO2 is causing an increase in pH from the old tap reading of 7.2 to the new tap reading of 8? with no apparent behavioural change in testing method?

But the original post pH gone up to 8 tap water is also 8. suggests tank and tap is at 8

His pH has gone up, from 7.2 to 8... Carbonic Acid, is an Acid.... going from a pH of 7 to 8 means the water is more Alkaline.

Good argument, I think my point would just be why bother putting them in a 10 gal, you are going to have to buy a bigger tank, save money and their stress (movement ect) and just buy the one larger one to begin with. I know not always practical, but food for thought.

The reason why I don't like using hot tap water for Water changes,

Yes you do need to treat is every time you change water When you do a water change, you should try to add water which is the same temperature as the tank water. you can do this by adding a heater to your bucket before adding to the tank, mixing hot and cold tap water to get the desired temp or...

Don't forget your pounds, shillings and pence...

that's poor advice from a LFS, it may be fine for the shark, but cause unnecessary stress and death in the fish held with it. It will have started to mature, a lot of fish species will become more territorial when they begin to mature.

I have never kept them myself, but I know a few people who have had them tell me they can be very territorial. This usually will happen when the fish begins to mature, so the fish has probably reached the Size or age of maturity.

This was an "in general" guideline for what you might expect. As I am sure you know the requirements are so varied between species It would be impractical to include it in the table. A quick google scholar search can bring up the macronutrient requirements for specific species. I tried to find a...

Hi and welcome, Nice to see another person on here who lives in Scotland!

Hi and welcome. Post some pictures of your tanks if you can, we'd love to see them

Do you test your own water or do you take it to a LFS? What were you last readings?

Right, we are all here trying to help you. Please don't see it as anything other than that. You clearly have been breeding you Betta's, great! And have some practical experience. What you appear to lack is the basic knowledge of the role genetics play in breeding fish. I am a fish scientist...

If we need more, I would be happy to volunteer.... If anything just to stop nick posting his bad jokes....:rofl:

Most people regularly overfeed, Fish used in Aquaculture to achieve high growth rates are fed between 2% and 4% body weight per day. For a fish which is just being kept in your aquarium you do not need to feed that amount. I see people in the hobby feeding their fish more than workers on a fish...

I think he is calling us smart @NickAu ? Please don't take my comments as telling you not to do this. But what I want you to understand is that it takes more than putting two fish in a tank to breed fish. A little bit of reading before you start can really help you to understand more about...

And/or wear some rubber gloves...

Just an FYI you can treat your plants before you add them to the tank, to remove any unwanted passengers into your aquarium. A lot of people use potassium permanganate, or bleach. Don't forget to rinse thoroughly before adding to the tank...

I agree with Nick, We research what our fish require when we are thinking of keeping them, we do all this before they breed. I can understand if they bred by accident ( eg if the fish are hard to sex for a beginner). But it doesn't take a quick google search, or to ask on here before the fact to...

How old is the test kit? might be expired?

Just a myth, high levels of water changes after the treatments will remove the medication, and if you are really worried about it add some activated carbon to your filter. That will help remove anything in the water. Yes It does contain formaldehyde, but this is at a level with is non-toxic to...

So, what should I feed my fish? The first thing that I would say to many people is research, research, research. There is plenty of information out there on the nutritional requirements of fish a quick google scholar search can provide you with a whole range of information. Once you know about...

Feeding rates, and feed conversion A large portion of aquaculture nutrition discussion is regarding feeding rates and feed conversion ratios. That is to say, how much you feed VS how much fish you get out. In many aquaculture species this is very close to 1:1 with tilapia being the closest to a...

Diet composition The composition of any diet is key to providing the macronutrients for our fish’s growth. In the hobby we seem to focus on the ingredients list this is the wrong way of going about this. In Aquaculture the focus is not on the ingredients, but on the proximate composition of the...

There have been quite a few posts recently about fish nutrition and many of these have been slightly misguided in their understanding of how fish nutrition works. So as I work as a fish scientist I thought I would help clarify some basics about nutrition and feeding in fish. There are two types...

There are two common reasons why you see deformity in you stocks. 1) poor genetics- this is the result of breeding too many related fish together. Breeding related individuals increases the risk of genetic caused deformities or problems hugely 2)poor adult nutrition or poor nutrition as a...

I don't at the moment due to current house restrictions, but I have done Algae (marine), Artemia, Copepods and Rotifers and snails for the puffers, before. I have never really tried worms ect.

It takes about 30 days (depending on water temperature) for the eggs to hatch. for Cherry's Keep an eye out for baby shrimp, if you have fish in the tank which will eat them, then you might not see any

Go for your 20 Gal, that's the minimum i would have them in. Even if my minimum was 10 gal I see no reason why a 20 would hurt, larger volumes are more stable ect. How many breeding projects do you have going at the moment?
