Before it goes in
- Crystal Red Shrimp needs at least 20 L (5 gal). The smallest size in this library that clears that is the 36P.
- Keep 10 or more. Below that it hides, colours down and is far more likely to be picked on.
- It leaves shrimp and small fish alone.
- It is the wrong size to share a tank with Betta, Goldfish and Angelfish: it ends up as food.
- It holds at 68–75°F (20–24°C). That shares a window with Betta and Cherry Shrimp, but not with German Blue Ram and Discus.
- Sources say not to put it in a newly set-up tank — give the tank a few months first.
- A group of 10 takes up roughly 16% of what a 36P will comfortably hold, so plan the rest of the stock around it.
What tank size does it need?
At least 20 L (5 gal). The smallest size here that clears it is the 36P.
How many should I keep?
10 or more. Fewer than that and it spends its time hiding instead of out in the open.
Will it eat shrimp?
No — adult shrimp and their young are both safe with it.
What water does it want?
68–75°F (20–24°C), pH 5.5–6.8, GH 3–6.
How long does it live?
1.5–2 years in a tank that suits it. That is how long you are signing up for.
Can it go in a new tank?
No. Sources say not to add it to a newly set-up tank — it wants a tank that has been running for months.
Good tank mates
- Tank mates from this library that share its temperature window, are peaceful and eat neither it nor its young: Cherry Shrimp, Bristlenose Pleco, Celestial Pearl Danio, Otocinclus and Ramshorn Snail.
- Plants that hold up with it: Hygrophila corymbosa 'Siamensis', Water Sprite, Anubias nana 'Petite' and Cryptocoryne wendtii.
