When you have lots of small fish, some will always eat more than others, ending up with their bellies bulging out. This is not healthy for them. The fattest of my Neons died of Dropsy once. It would just eat and eat without any constraints, until it became extremely fat and got Dropsy. Though I never overfed my fish. It was just that the fat Neon would eat fastest of all fish, snatching up whatever the food she could and as fast as she could.
I guess there is not much you can do about these occasional glutton fish, lol. But as with any fish, overfeeding is not healthy. It's best to feed all your fish
very small amounts, 2 - 3 times a day, that's it. Some people feed only once a day.
How many Harlequin Rasboras did you get? They're beautiful fish
