  1. A man is found guilty of keeping live sharks in his pool and offering them for sale online By Maria Morava and Scottie Andrew, CNN
  2. https://www.sciencealert.com/cuttlefish-can-pass-a-cognitive-test-designed-for-children A Cephalopod Has Passed a Cognitive Test Designed For Human Children MICHELLE STARR 3 MARCH 2021 A new test of cephalopod smarts has reinforced how important it is for us humans to not underestimate animal intelligence. Cuttlefish have been put to a new version of the marshmallow test, and the results appear to demonstrate that there's more going on in their strange little brains than we knew.
  3. After getting this puppy home form the $1/gallon sale awhile back I realized it had this sticker on the bottom. Research from others with the same question would indicate it is not tempered. I can't find an indication one way or the other on the Aqueon website. I am trying to dig up a polarized filter for my camera I know I have somewhere but I was wondering if anyone had seen this label and tried drilling?
  4. Warning I've crashed every Daphnia culture I've fed anything except green water. Make sure to start side cultures when experimenting with food.
  5. I was not getting nearly the hatch rate with the Coop eggs as I was with the other major brand, let's call it brand X but we all know it is. Hopefully the secret test will help more but I have gotten it up with a few tricks. 1) they like it hot, if I get it up to around 84 degrees they hatch more. 2) they like more minerals and adding Epsom salt in with the rock salt helps. I am still not getting the same hatch rate. 3) don't overfill the amount of eggs, I hatch 3/4 to 1 teaspoon at most in 1L of water. This is in my standard 1.5L soda bottle hanging setup which is identical to Dean's old setup. I am still not getting the same hatch rate but with the better egg separation its still worth it. My hope is Dean's secret test is not marine salt. I need to pay $5 for 20lbs of salt (big box store pure rock salt) not $20 for 20lbs of marine salt which is the price I see online.
  6. This weekend I drilled most of the 10g aquariums. Turns out it really is easy after all.
  7. Well the Coop carries an internal K1 filter. https://www.aquariumcoop.com/collections/filtration/products/ziss-bubble-bio-moving-bed-filter
  8. I'm struggling to get swords to grow in my 55. To be honest they grew better before I got the Fluval 3. I've got it pretty cranked down with a long photo period. I heard swords like a long day. Not sure. I also give root tabs once a month. The amber and red are to give a more sunrise and sunset look. Any advice is appreciated.
  9. I have had Otos bred on their own in a couple of tanks over the years. I have had them survive when there is plenty of surface algae for them to graze on. If you don't have any in your tank maybe you can put a small piece of wood in something else under intense light to try and grow some quickly.
  10. Unfortunately I have no advice. i love these fish but have not yet kept them. I'd look up similar tetra species if you can't find something on them specifically. I know there are a few techniques for tetras in general.
  11. Nice and lucky. We have so few LFS here and they are all far apart. Every one I've inquired with is always "we take rescue fish only". I am getting into breeding more now and would like a place to send them for re-homing, store credit would be secondary.
  12. So after further experimenting I can control the flow enough with the 1/4" shut-off valves I can put at each tank. It's maybe not ideal as it leaves room for human error but I can still always try the restrictors later without changing anything else. Here's a mock-up:
  13. Thanks that is very interesting. I had not come across those constrictors before, I'll lok into them.
