So, because I don't have a thread about the dwarf Seahorses, here's an update.
Had a hiccup yesterday, combination of gorg issues, temp too low, flow too high..... things are better today. Also, got a bigger cube, now a giant 3 gallons! I want to incorporate a way to hide all the cords and the air pump so I'm going to make a small stand/platform for it. I think 2" is enough to clear the air pump and shove the cords under. I had some scrap wood that's perfect for it. Ordering a light also.
Found out brine shrimp eggs can be very different. New type hatches so much better.
And lastly, both babies are eating constantly. Cute.
