What it is

OEBT is short for orange-eyed blue tiger. A glassy blue shrimp with stripes and orange eyes. Sold under the name Caridina mariae.

What water does it need?

Tigers sit in the middle, fussier than Neocaridina (the cherry shrimp family) but easier than bee shrimp (crystals and bolts). They want soft water that is a little on the acid side. They can take a wider range of minerals than crystals or bolts. And they do not need the near-zero KH (the part of hardness that holds pH steady) a bee does. Soft tap water suits them. So does RO water (tap water with everything filtered out) mixed with some tap water.

In the table: pH is how acid or alkaline the water is. GH is the minerals in the water. KH is the part that holds pH steady. TDS is everything in the water added up.

pH6.2 – 7.2
GH (hardness)4 – 8 dGH
KH (carbonate)0 – 4 dKH
TDS (total minerals)150 – 250 ppm
Temperature20 – 25 °C

If your tap water is hard and you don't want to run an RO filter, the Neocaridina colours are happy in harder water and cost less.

The full story, including cycling your tank, copper and which fish are safe, is on the water & care page. Read it before you order, not after.

Will they breed? Can I mix them?

They breed, but slowly. Six or more in a steady tank will have babies in a few months. Three can, but it takes longer.

Keep one kind per tank. This shrimp will breed with the other tiger we sell, and with every bee shrimp (bee is the hobby name for crystals, bolts, dragons and fancy tigers). Tiger and bee babies are tibees (a mix, not a pure copy of either parent). You cannot breed the pure tiger line back out of them. The mixed babies are healthy, but the pattern is gone for good. Cross two bee kinds and you get muddled shrimp with weaker colour and pattern. They never sort themselves out again. Cross a tiger with a bee and you get tibees (a mix that looks like neither parent). There is no way back to either parent kind. Neocaridina (cherries) and Caridina (crystals and tigers) are different groups of shrimp and cannot breed with each other. So you can keep one of each in the same tank, if the water suits both.

What does it cost delivered?

$22 a shrimp. We sell them in packs of 3. One foam express box costs the same to send whether it holds 3 shrimp or thirty. So 3 delivered is $95.99. That is $32 each with postage in. The same $29.99 post carries a bigger box too. It drops to $9.99 once your shrimp come to $149. So the more you order, the less each shrimp costs. Everything goes out on a Monday or a Tuesday, packed that morning. Every shrimp is guaranteed to arrive alive. The guarantee is short, and it says what it does not cover.
