  1. They get a bad rap, but if I listed them as 'freshwater sea anemones' I bet I could sell hydras on AquaBid.
  2. Nothing to worried about at all! Like @gardenman says above, it is just all the little microscopic fauna that really healthy aquariums have. It is actually a very good sign.
  3. Me and my boys saw an emu, it was a life bird for me.
  4. Maybe, but it could be that zero doesn't look like zero, or that any aquarium with any amount of life in it will never truly register zero.
  5. Could be cyclops or seed shrimp? Here is a video I shot that has, seed shrimp, cyclops and scuds in it.
  6. I don't think I ever get a nitrate test that looks like zero!
  7. I last kept and bred paradise fish in the 1980s (very, very tough hardy fish) and I would say that those are all males. My memory of females was that they had noticeably shorter fins, something like this:
  8. pH = 7.4 pH High = 7.4 Ammonia = 0.75 Nitrite = 0 Nitrate = ~0
  9. The rocks will develop a nice patina of bacteria over time. This is very healthy for the ecosystem of your aquarium. I don't think I have ever cleaned my rocks because 'prettier' rocks were nowhere near as attractive as a healthy aquarium.
  10. That could well be true, but it might not be important. If the filter moves enough water through the gravel to keep the beneficial bacteria in contact with the nutrient waste your aquarium is producing, then you very likely have more than enough biological filtration to handle your bioload. Do anything seem amiss?
  11. I keep a lot of very happy aquariums without heaters, filters or even cycling them. But that doesn't mean that heaters, filters or cycling are hocus pocus money grabs or that people who use them are uninformed. It just means that there is often more than 1 path to achieve a result.
  12. I have a similar plant that I wild collected last fall. You can see some of the leaves look a lot like your leaves. I think it mainly a humidity issue. In the wild where I collected them, it was basically a low lying swamp/ditch with much high humidity than my house. Here is where I got them.
  13. I know, tubers and bulbs are so confusing! Bulbs definitely have things like basal plates that tubers (which are swollen stems) do not. The illustration below is of a tunicate (meaning arranged in layers) bulb. But if I remember correctly, lilies are imbricate (meaning overlapping like roof shingles) bulbs.
  14. And a limitation in a critical nutrient can cause the plants to be stunted even if other nutrients are available in abundance.
  15. Males guppies aren't picky when it comes to mating. Males have been known to mate with anesthetized female guppies. I have seen them trying to mate with big female swordtails so never underestimate what is going on their tiny brains.
  16. Do you have shrimp in the tank? It sort of looks like a shrimp molt.
  17. Looks more complicated than a fungus, but honestly I have no idea what it is.
  18. @Irene has a good article on this. https://www.aquariumcoop.com/blogs/aquarium/plant-nutrient-deficiencies?_pos=1&_sid=727c4d3e8&_ss=r This chart is useful too:
  19. As @ererer notes above Apistogramma do hybridize within species groups i.e. commbrae-complex, regani-complex, paucisquamis-complex, nijsseni-group. Chart from Mike Wise article. I don't know how likely the hybridization is but I don't think it is impossible as they are in the same 'trifaciata' lineage (I also haven't tried it so I don't really know).
  20. @Colu is local to the UK. I bet he has a UK friendly solution. 🙂
  21. I plotted those in MS Excel, but I also do have digital monitors in those same aquariums (Neptune Apex) that plot nice graphs of temperature and pH also:
  22. Not everything works like the textbooks say. This aquarium was well behaved (and had fish in it while it was cycling): This similar (with fish) tank had a different but equally successful experience: The rules have more leeway than is imagined.
  23. This early work by Dr. Innes has to be on of the best of all time. I uploaded it earlier to the Forum:
