I used to have 5 of these guys, they were sold 5 for $3. However, one of them died when being put into the tank (for some reason, its stomach area tore), and the 4 lived on. But the strange thing is that I now find that I have only 1 of them left! I suspect they were eaten by the larger Red Eyed Tetras in the tank. These fish come to local fish shops only once in a long while and they definitely add lots of variety to the tank. Should be alright to keep with neon tetras, chocolate gourami, glass catfish, albino tetras, etc.

I have a school of 9 of these wee rasboras in a heavily planted tank with 2 corys, an oto and 2 gouramis...these guys are a kick. They are fearless, friendly, peaceful and very active...great eaters. Mine eat flake, liveworms and I've seen them pick up the wee snails and shake them like terriers. When I have to work in the tank, all the other fish flee, but these guys check out my hand and want to see what's going on. They are gorgeous too, a beautiful salmon pink...the males get almost red.

I have four of this little rasbora species, and I find that they are such a fine little fish, very active and a joy to look at. They live in a small 20 liter well planted tank with quite a few red cherry shrimp in all sizes, and that's a good combination. I would be careful with other tank mates as I think they could easily be eaten. They are easy to feed, and not shy at all. When I change water it looks like they like the new fresh water and immediately the males starts hunting the female, which I think unfortunately is in a ratio of 3:1. They should breed easily, but may eat their eggs and fry if you don't do something to prevent it, so I am trying now with a bit of Java moss, to give protection to the eggs.

I have 19 of these in my planted tank. They adventure off on their own or in small groups, but if scared, they quickly swarm together. Overall, they are very active and spend a lot of time playing in the HOB outflow. On more than one occasion, I've had to net out one of these guys from the HOB. They enjoy the flow so much they actually swim up through it. They eat flake foods readily. I just crush it up a bit before feeding. The best thing about them is that they're so small that it makes small tanks look much bigger, as it preserves the sense of scale.

I have 9 of these with 3 pygmy corries (Corydoras pygmaeus) in a 20 liter tank with a mixture of live and silk plants. This was supposed to be a quarantine tank, but the tank cycled and the fish did so well, I added Eco-complete substrate and allowed them to stay there permanently. They are wonderful little fish for a small tank, allowing you to keep a shoal of them while maintaining good water conditions as their bioload is equally as small as their size. I have found them to be surprisingly hardy with none dying or becoming sick in the 3 months I've had them. Water changes are about 50% every month. They will quickly show if they're stressed by their colors. Mostly, they are a very deep pink to red color; however, major changes such as large water changes can cause them stress in which their colors will become rather pale. This will only last an hour or two, and they will usually color up again when fed. Their favorite foods are frozen daphnia, frozen baby brine shrimp, and First Bites, all Hikari brand. I also feed them frozen bloodworms (cut up), frozen spirulina shrimp and basic flake foods crumbled up into very small pieces. They tolerate the bloodworms and shrimp, but love the rest. The fish will at times shoal together while at other times wander off independently; they appear comfortable either way. They are very peaceful and show no aggression of any kind, not even chasing. Overall, their beautiful color, hardiness, easy care, peaceful temperament, and very small size makes them a wonderful choice for a nano tank.
