Update

The first thing I'll tell you today is that the sick guppy died. We buried it in our backyard. R.I.P.

I was finally able to put the pictures on the computer, so here they are:

 A pic on the guppies. The focus is a bit off on the red-tailed one, the tank is sparsely planted.

 A pic of the corner of the tank. A barb and two neon tetras. They hang out with each other very well.

 Another with the neons.

 Another.

 A full view of the guppy tank. This was before the sick one died, before we moved it into the quarantine.

 A close up of 4 guppies. This was taken during the day, so the focus was just right.

 The crayfish tank. (Sorry about the sideways pic. My mom carefully made the crayfish homes.

 The white angelfish. The one on the front has a shrunk gill, I'd say injury.

 More tetras/barbs.

 The tetras don't stay in that other corner all the time, this one shows them on the other side. I also have an algae problem with the tree and gravel, we're hoping the two otos and the pleco will eat them.

The barbs. Actually, the focus is on the java fern in the background, which is doing well at the moment. We checked the java fern below this one and mysteriously, some leaves had disappeared. The gourami probably chomped at it.

Thanks for reading, next update coming soon.
