Re: Help #1
If we can get the actual readings from your daughter-in-law / you, that would be extremely helpful. Readings can seem "fine" but, for example, a tiny amount of ammonia or nitrite over the course of several weeks or a one-off high nitrate reading could be enough to make the fish skittish, and the light being switched on could be "the final straw" which causes this behaviour, if that makes sense. That's why it's really helpful to get the full grasp of the situation to identify or eliminate the possibility of something which may be predisposing the fish to behave like this.

If it does turn out that all other possibilities can be eliminated, and there hasn't been a particular incident which you can think of that may have made them more skittish (e.g. one of the fish or tank inhabitants not being compatible with the others and having terrorised the fish as a one-off event or only starting recently, a sudden loud bang near the tank, a child shouting or running in the vicinity of the tank, complete changing of the filter media causing a new cycle to start, being away for several days in which the light wasn't on at all, the room being in pitch darkness and quiet and then suddenly the main light or the tanklight switched on), then it's extremely odd but not outwith the realms of possibility that they've developed an aversion to the light.

If all the aforementioned possible factors can be eliminated (we can help work out if this is the case if you can answer the questions and I would really encourage this), then it's not a necessity for the fish to have a light by any means - it is a necessity for live plants, though, and cosmetically for humans' enjoyment of the fish. It is also possible to buy timers for LED lights which can create a sunrise and sunset effect which would be less of a shock to them.

Re: Help #4
Hi I’m not sure of the readings my daughter in law checked them all using water test kit and all readings were fine the problem only starts once light is switched on it never used to happen I’ve had these 3 months now first 2 months they were fine with light on but now as soon as light goes on they seem panicked .

Re: Help #5
I can't see the photo, unfortunately, but, in order that we can get a full grasp of the situation and give appropriate advice, can you let us know the following:
* test results for ammonia, nitrite, nitrates, PH (and GH and KH too - ideally from a test kit but, if not, let us know the CaCO3 and German degress hardness readings from your water company's website for your postcode);
* size of tank - dimensions and water volume;
* how you cycled the tank and when the process was completed;
* what fish you have and how many of each species;
* water change regime.

Thanks. :)

Re: Variatus Platy Strange Behaviours (unsure if normal or not) #6
That is indeed shockingly poor advice that you've been given but unfortunately not that uncommon either.

In order that you can understand fishless cycling better, it might help to think of it as preparing the filter to become ready to be able to process the fish's waste (ammonia). This article explains the process - and what you ought to have done https://www.fishkeeping.co.uk/articles ... hless-cycling-article.htm , rather than simply running the filter which has achieved nothing other than ensuring that its motor, etc, is actually functioning.

A liquid-based test kit is absolutely crucial for seeing you through the cycling process - not test strips which are not sufficiently accurate and the general 5/6-in-1 ones don't even have the crucial ammonia test on it while the strip-based ammonia test is notoriously difficult to read.

Generally, the problem can be addressed as follows https://www.fishkeeping.co.uk/articles ... ammonia-nitrite-spike.htm (but safer not to put the fish through this fish-in cycling process). HOWEVER, given that a 24-litre tank is not suitable for variatus platies - their requirements are here https://www.fishkeeping.co.uk/modules/ ... sheet.php?caresheetID=202 and http://www.seriouslyfish.com/species/xiphophorus-variatus/ - you would be quite within your rights, for welfare reasons as well as being given inappropriate advice and mis-sold fish unsuitable for the tank size, to return the fish to where you obtained them, showing them the good quality evidence within these links of what the species require in terms of minimum tank size as well as what fishless cycling involves, etc.

Your decision then is to EITHER continue to fishless cycle the tank/filter but in the knowledge that it's only suitable for snails and shrimp rather than fish OR buy a suitable-sized tank and cycle its filter and then buy new fish whose requirements you can offer in terms of tank size (etc) once that process is complete.

Hope that's helpful.

Re: Variatus Platy Strange Behaviours (unsure if normal or not) #9
I havent got a test kit at the moment but I will be buying one tomorrow asap to be safe, the tank is 24L and for cycling I was advised when buying the tank to run the filter and oxygen for a few days so have done that before buying the fish, water was treated also with conditioner, hoping pets at home havent given me wrong advice...

Thanks

Can you post back with the tank size and test results for ammonia, nitrite, nitrate and pH, please? How did you cycle the tank?
