Description : Characteristic shape of the shrimps belonging to the Caridina genus, the rostrum is long, slightly curved and very spiky. The background colouration is variable depending on specimens, going from deep burgundy to orange-red. A few orange dots are located on the uropods and a few yellow thins stripes underline the edges of the cephalotorax at the level of the junction with the abdomen as well as the edges of the third, fifth and sixth segments of the abdomen. The presences and the intensity of these dots are variable according to each individual. The ocular pods are very well developed and bright yellow which is an unusual characteristic. The propodus and dactylus of the chelipedes (See article about shrimp morphology) are also coloured in yellow, enhancing each of the coordinated movements of the appendages searching for food. Caridina spinata is a very small and timid shrimp but offers an exquisite colouration.
Behaviour: Excellent gregarious specie that must absolutely live in groups of 6 individuals of the same specie, no less. This shrimp is relatively shy and will appreciate hidings with shadows in habitat. She will need to find some refuge between rocks. A few plants can be added to the habitat : Ceratophyllum demersum, Java moss, Aegagropila linnaei (ex : Cladophora) or Ottelia mesenterium (and other rare plants imported from Sulawesi).
Life span : Unknown when index was made.
Feeding habits : Few informations are accessible about their feeding habits. However this shrimp from Sulawesi seems less picky than others and will take flakes and bottom tabs containing spirulin. It spends a lot of time collecting it’s food with uninterrupted movements of its little claws. A base of Java moss or Cladophora will always be much appreciated.
Sexual dismorphism : The female are slightly bigger than the males. This faint difference will be hard to establish and decipher.
Reproduction : This specie uses a direct type of reproduction. To this day we do not have access to any precise information concerning the reproduction of this specie. The eggs are relatively big : about 0.70 - 0.77 mm and few per incubation.
Specificity : The Caridina spinata is part of the shrimps imported from Sulawesi at the beginning of the year. Without a doubt extremely pretty, they are very specific about their maintenance and must have the very best conditions. Physical-Chemical parameters must not be neglected or taken lightly. However this Caridina from Sulawesi has a better reputation than her cousins, seemingly easier to acclimate. Endemic to Sulawesi, it is crucial to put all the chances on one’s side to achieve breeding of this shrimp therefore limiting collection of wild individuals.
Other specimens are identified as Caridina spinata or Caridina cf. spinata. The colouration criteria isn’t always a distinction motif between species and can simply show different varieties. We will need to wait for the specialists to accomplish their studies to be certain of the link to the Caridina spinata specie or a new specie. The very different aspect of the Caridina sp. red Fire, would tend to go towards the second option : meaning another specie to study and detail.
