Just a quick update. This tank is doing pretty well, never have added anything else to it, well a did throw a couple plants in the HOB, but other than that it is just chugging along. The Crypts love the dirt and the Marsilea is still spreading.
The 2 harlequins have been doing the upside down wiggle dance a lot, but I have yet to see any eggs. Well, last week when we were sitting down to eat dinner (this tank is on a shelf next to the dinner table) I look at the tank like always, and there is a baby!!! It is about .5cm long, it is so cool. First baby I've had. I have heard that Harlequins are kinda hard to get to breed, so I never even thought about it, but having seen them doing the mating dance I kinda got my hopes up, but like I said, I have yet to see any eggs, but I've got a little Harlequin swimmin around! It'll be hell tryin to get a pic but I will see what I can do.
I changed out the HOB for a sponge to reduce current and he seems to utilize more of the tank now.
