Right, we have now gotten our first batch of fish.
3 Guppies
9 (of 10) Neon-Tetras (one died in transit)
2 Sword-bearers
It took about 5-10 minutes before the cats spotted them.
It also took about 5-10 minutes before the cats lost interest again.
Gonna wait about two weeks and add another batch of red neon-tetras and a few other Guppies and sword bearers.
A month or two later we get the bottom feeding vacuum cleaners.
