  1. Hey everyone, Happy New Year. Wow seems likes ages ago when I started my goldfish blog on our dirt planted goldfish tank. Well we have some news, our very first ranchu baby goldfish hatched and are slowly growing up. We plan to rehome our non-ranchus and at some point get some nice red and white ranchus for any future breeding. Thanks again to everyone here for your helpful comments over the years. Cheers.
  2. Yup the female Cheddar is certainly not the perfect type ranchu. But they were a male/female pair at a reasonable price, so I figured its a good way to get started with ranchus. Got to say I'm really loving their Fu dog looking faces and interactions so far.
  3. I finally found some ranchu goldfish to try and start our breeding project. Wish us luck!
  4. Thanks for the advice, I'll go with the 10G. And when i went up in the attic to bring down my 23 year old 20G to see if it was still water tight it turned out it was actually a 30G lol.
  5. Is it better to quarantine a 3 1/2 inch goldfish in a 10 or 20 gallon tank? Which would you all do?
  6. Wow waiting four weeks seemed to take forever, but we finally put our two new goldfish into the 125G tank to keep our Ryukin “Ranger” company.
  7. Here’s a two minute video of Ranger, our red and white Ryukin, after six weeks in our tank. So far so good.
  8. My 125 gallon dirt planted goldfish tank used to have a good mix of water lettuce, water wisteria and frogbit. But when I upgraded my lights to Fluval leds (Plant 2.0 and Aquasky) the water lettuce and wisteria started to turn brown and the frogbit took over as the last remaining floating plant. The frogbit used to send up flowers about every day, but have taken a bit of a hit with the absence of fish in the tank for two weeks and with our new fish Ranger now heavily eating their roots. I currently have the lights only 2 ¾ inch from the water. I’m wondering if I should raise it a bit and try adding some water lettuce and wisteria back into the mix. Am I right in thinking the lights might be too close for certain floating plants?
  9. Thanks for the response Shakaho. I read Walstad’s original book four years ago when I was first setting up the tank and actually re-read her updated version last year. Obviously I’m doing a modified version since I still have two box filters rated to 120 gallons to maintain good oxygenation and periodically do 30% water changes. I would of course agree that a sudden loss of fish would most likely be caused by something toxic in the water or food. But the reason we don’t think that was the issue was because the tank tested its normal zero ammonia, nitrite and nitrate. The only significant thing that could have rotted would be a couple of nerite snails, but they don’t burrow down into the 1 inch of gravel. In the first six months of our tank we would see bubbles percolating up from the organic potting soil as it broke down, but that never seemed to be a problem. It doesn’t really seem plausible that the small and consistent amounts of fish food, fish poop or decomposing plants that might get under the gravel, which the fish are constantly pecking through, could cause a lethal release of anything to kill off two healthy fish in a 120 gallon heavily planted and well oxygenated tank, but we could be wrong. The reason we suspect the spiral snails was that Big Red was always searching through the top leaves looking for algae and (we now realize) snails. Once she was gone for a month the spiral snails, for the first time, were able to come down onto the lower leaves and glass. Once Lighting and Scout, who were always much more likely to forage in the mid level to bottom of the tank, had access to them, we think they began feasting on them for the first time. At least that’s what we suspect, hard to know for sure.
  10. Hey everyone, here is the video about losing all three of our four year old goldfish. We have a new Ryukin in the tank now checking things out to see if everything is ok. Got a 10 gallon quarantine tank setup for the next fish we put in. After that I think I might give raising some nerite snails a try. And in case anyone missed it here is the video with the story of our four year dirt planted goldfish tank.
  11. I would also recommend reading Walstad’s book. Based on my experience keeping three comet goldfish in a dirt planted tank for two and a half years I would recommend full size amazon swords, the bigger the better. It took them more than a year, but eventually my growing fish pulled up or ate everything else I had planted. My Java ferns have done well because they were tried to driftwood or superglued to rocks. At some point I might try anubias again, but I would attach them all securely to a structure. I think the key factor for the variation on the Walstad method I’ve been doing has been the constant growth of the floating plants: frogbit, water lettuce and some surviving water sprite. I still cull out a cup of them every week or so. Looking forward to seeing your updates.
  12. It's harder to play diving submarine with your camera with a hood on. Just saying...
  13. Justin Algae just needs nutrients in the water and light to grow. So if you add your nutrient-rich dirt, gravel and water and run the lights before you have plants you're giving the algae a head start. If possible I'd add some floating plants to your list. They're the best thing possible for sucking up excess nitrogen and nutrients since they can get their CO2 directly from the air. I've had the best luck with watersprite, water lettuce and frogbit. I've had good experiences ordering online from Peabody's Paradise and Planted Aquariums Central. I'd also highly recommend getting some Nerite snails after awhile. They do a great job of cleaning any algae you may get and breaking down any missed fish food or wilting leaves into a form the plants can more readily use. They lay tiny white eggs but they won't hatch in freshwater so you don't have to worry about them become a pest.
  14. Justin My local Lowes didn't have the Miracle Grow that many people use. So I just used their generic organic potting soil that had the same basic stats and it worked great. I wouldn't recommend anything that has limestone or fertilizer in it. I think the ingredients in my organic potting soil was something like poultry litter and feathermeal. One small drawback to the Miracle Grow organic potting soil is that many people report getting lots of floating debris in it, which I was lucky enough to not get. I would recommend that after adding the dirt you only add a few inches of water and let it set overnight. If it doesn't mostly clear up on its own I would recommend vacuuming up all the floating debris BEFORE filling the whole tank with your substrate and water. And the main thing to remember about a dirted tank is you want to add as many plants as you can afford from the start so they can outcompete algae for all the nutrients that dirt will be slowly leaching into the water. And DON'T use your lights until you actually start planting plants. If you haven't already I would highly recommend watching some YouTube videos at Justin's Fish Tanks to get lots of good info on dirted tanks: https://www.youtube.com/channel/UC4j90aZYe6v7J4Yb6qpbiLw If you do some basic research and plant enough suitable plants you should find that dirted tanks are actually way easier and less maintenance than about any other way of keeping plants. You'll spend most of your maintenance time pruning excess plant growth. Happy dirting!
  15. Thanks for the comments everyone. By "natural" I meant an environment more like what goldfish/carp have typically lived in for the last several hundred/thousand years: dirt, rocks, submerged wood, aquatic plants and invertebrates with fairly stable or at least slow changing water conditions full of dissolved organics. I suppose the main thing (other than size obviously) my system most misses would be algae for the goldfish to eat -- but I can live with that -- that's what the Rapashy Super Green is for. The way Walstad tried to measure her system was to weigh all the fish food she put in and compare it to the weight of the plant mass she was taking out. I typically take out at least one full cup of mostly green plant mass a week. That at least seems to be more than the mass of fish food I put in, but I haven't tried to weigh it all out. Btw here is the link to my tank's goldfish blog: http://www.kokosgoldfish.invisionzone.com/forum/index.php?/topic/116731-andrews-125-g-dirt-planted-goldfish-tank/ And here are some pictures.
