  1. Hi the plants have been there for quite a few days, so far it seems to be fine. Also, one of my friends has agreed to come to my flat next weekend (right in the middle of my holiday period) to feed the fish, so it should definitely be ok now, the gap would only be around 4 to 5 days, rather than 10 days. I won't need to add in any holiday food.
  2. I bought 2 moss balls and a bunch of elodea plants. I have also got some holiday food. Should I also put in a small piece just in case before I leave for holiday? I don't really like fish holiday foods because they are generally poor quality (and my goldfish is used to better quality food) and potentially they can have a negative impact on water quality. This is why I thought about using "natural foods" like water plants instead. As for automatic feeders, I've considered it but the issue is that there is no way for me to keep my tank lid closed if I install the automatic feeder, I'd have to keep the lid completely open, and I worry about the fish jumping out. I lost one fish nearly 2 years ago this way, even though at the time there was nothing wrong with the water quality. As long as the goldfish won't actually starve to death (now that I've got plenty of edible water plants in the tank) I'd rather not risk opening the lid and keep it open for 10 days straight.
  3. Hi I have a question I'm going away on holiday for about 10 days next week. Because I live by myself there won't be anyone who can feed my single goldfish. I plan to buy a few moss balls as a kind of "natural holiday food" for the goldfish, rather than the usual holiday fish food one can buy in stores, which are generally quite poor quality. Would the goldfish be able to eat some of the moss ball and not go hungry? Thank you
  4. I didn't buy the snail, it was a "stowaway". It's now in a small tank with white cloud mountain minnows and the temperature is not high. The snail also looks smaller than the typical adult size (according to online sources I consulted) so even if it was female I don't think it's going to reproduce anytime soon.
  5. I've put it into one of my other tanks. I think the water parameters and temperature are ok for it. I can't find it anymore but it's probably among the gravel somewhere. I don't think I need to feed any special food for it as it can eat the micro pellets for my fish that are left overs.
  6. Hi I just bought a few neon tetras for my nano tropical tank and I seem to have got a "stowaway" small snail. Does anyone know what species of snail this is? (See image below) Thanks
  7. I'm not much of a photographer and this is a newly set-up tank...(though in terms of style with goldfish tanks I generally do prefer a "minimalist" approach)
  8. That's still quite a lot... Generally any flow rate that is more than 10X the tank volume is considered to be "strong". Your total flow rate is 300 gph which is 15 times the size of your tank (20G). But thanks for the info anyway. Now I have some concrete idea about this.
  9. Some photos will come soon...
  10. Could you tell me what is the flow rate of an AC 10 filter?
  11. Going by your logic here a weaker UV light might actually be better than a very strong one, because a less powerful UV light can weaken microbes but would not drastically change the environment like a very strong UV would. So it would make more sense to use a weaker and smaller UV light as a supplement rather than relying on a powerful UV to kill off all or most potentially harmful microbes. It's like with humans, it's a good idea to live in a relatively clean environment (even though such clean environments are products of human civilisation and are not technically "natural"), but it's not good to live in an environment that is completely pathogen-free, because it would cause one's immune system to degenerate, so after a while when one has to go to an environment that is not pathogen-free, just a little bit of pathogens might have a very significant or even in some cases lethal effect. My point is that I think UV can only be used in fish tanks as a supplement, not the main method of avoiding diseases.
  12. Ok. I mean quantitatively, how strong is "strong"? A flow rate that's over 10X the tank volume?
  13. Well, I don't really agree with you, and I also don't have much interest in any kind of abstract philosophical speculation, but I don't want to have a debate on this either.
  14. Sorry I didn't know about this particular forum rule. None of the other forums I visit have it. As for the other point, I don't see your point. I think in a free forum anyone can state any opinion or view as long as it doesn't break the forum rules or constitute a personal attack. Just because something may not "make sense" to you or you don't personally agree to it doesn't mean one can't make the point. That doesn't seem to comply to the principle of the freedom of speech. I know you personally don't like UV sterilisers but not everyone would agree with you. So yes I will stick to my original point. What she said might "make sense" as a "rule of thumb", but it's not scientifically verified. I don't think there is any solid evidence showing that UV light has a negative effect on beneficial bacteria in the long-term (as opposed to in a tank that is newly set-up). Just because something seems to "make sense" in a "hand-waving" way doesn't mean it is scientifically true. Science doesn't work via philosophical speculation, but solid empirical evidence.
  15. I think I used to have a photobucket account several years ago but I forgot all about it since I never really use such things. Seems I would have to create a new account now.
  16. This is info from another forum: [link removed by DNAlex] UV sterilizer/clarifiers emit UV-C rays... also know as UVC radiation... The bulb emits radiations that affects whatever passes in front of it. The stronger or more complex the organism, the longer it will take for the radiation to kill it... This is why we suggest slow flow rates for killing parasites (more complex organisms) and faster flow rates for killing algae (very simple organisms). UVC radiation will kill bacteria that flows through the UV light. "Beneficial Bacteria" as we so often call it, grows on surfaces. This includes substrate and bio media, but also includes mechanical media, decor, pipes, the side walls of the tank, the side walls of the filter boxes, etc, etc, etc... When we start a new tank, it's a good idea not to hook up a UV light right away. This is to help allow bacteria to migrate throughout the system. It will become dislodged from one area and float to another area. Once the tank is mature, the very small amoutn of bacteria that is killed while migrating through a UV light will be inconsequencial.
  17. I do think as a "rule of thumb" (i.e. not exactly scientifically verified), it is prudent to not use UV in a relatively new tank.
  18. Once it is mostly filled, when bacteria/archaea divide, typically one daughter cell remains in the biofilm and the other floats free until it lands on a less crowded surface. How can you be so sure the ratio here in 1 to 1? It might be a different ratio. Maybe most of the bacteria stays on the filter, or perhaps most of it gets into the water.
  19. Just a short general question here: Do guppies prefer stronger currents or weaker ones?
  20. I assume you are referring to rectangular tanks. I recently bought an used Juwel Trigon 190 which is 50G, but it's a corner tank (its shape is one-quarter of a spherical disc or cylinder) and it has no centre bracket. But then I'm pretty sure that even on a completely new Juwel Trigon tank there is no central bracket either, since I've downloaded and printed off the instruction manual for this tank.
  21. Is there no way to directly load photos onto this website?
  22. I got a lot of my stuff on eBay. There is a much bigger selection of products and sellers on eBay than on Amazon.
  23. I think it's probably better to use cotton strings than rubber bands as they are not as tight and leaving a rubber band in aquarium water probably isn't ideal. Cotton is a more fish-friendly material than rubber.
