The 3 Inpaichthys kerri are chasing each other and the Silver Hatchetfish seem OK. though not particular active as you mentioned, but seem to hang around the surface and half way down.
I did have 4 Siamese algae eaters, took 3 back to the LFS but cant catch the other one, as soon as I put the net in it disappears into the plants. Not sure how to catch him.
I have one baby Platy as well I noticed it last weekend after a 4 day break, could be a couple of weeks old as its about 6-7 mm long.
That's sufficient space in your tank to increase the groups. They both need it. I'll detail this a bit more for you.
Shoaling fish live in large groups for several reasons that I won't go into, except to say that they have evolved this way and it is an essential aspect of their well-being. Minimum numbers (six is usually suggested with most species, some differ) have scientific basis, as studies have now proven that all of these shoaling species will frequently develop problems in fewer numbers. Usually it is aggression, even among otherwise normally peaceful fish, but sometimes the fish responds by taking the opposite route, and sort of weakens away. Sometimes they seem to manage somehow, but of course we can't say they are actually in as good health as they would be with better numbers. So it is always best to provide as many as the situation allows. It is even better to slightly overstock the tank (when necessary) in order to achieve this, rather than having too few; the fish will be less healthy with fewer. Often this is not discernible until it is too late, and the fish just die. Stress is the cause, brought on by inappropriate conditions.
Hope this is useful.
