Sometimes good things come in small packages. Such is the case withCanthigaster Valentini,更名为托比(Toby)的托比(Toby),黑色饰演的托比(Toby)或瓦伦丁(Valentin)的托比(您还可以看到在各种来源中代替“ Toby”的“ Sharpnose Puffer”)。该物种的总长度仅达到约4英寸,通常适应水族馆的条件,可以为具有适度的系统和中级爱好体验的河豚狂热爱好者做出一个理想的选择。
身体特征
很难用书面描述对托比的身体外表进行公正,但我会打扰它:这条鱼在某种程度上被高盘子的眼睛和中等伸长的鼻子压缩了一定程度上(因此是“尖锐的”绰号)。它的基本色素为白色,背面有一系列棕色的标记,中间的两个向下延伸至腹部。小橙色至棕色的斑点沿着鱼的腹侧半出现,脸上散布着薄而褐色的线条。
成年男性往往比女性大,可以通过源自头部并沿背部延伸的薄绿松石线来区分。还有其他区别特征,但是此功能可能是最容易识别的特征。
作为河豚,C. Valentinidoes have the ability to inflate its body when threatened. This response is very stressful to the fish and should never be encouraged. To avoid stressing a specimen when moving it from one tank to another, gently coax it into a rigid container instead of attempting to capture it by net.
最真诚的奉承形式
值得注意的是C. Valentinihas a mimic species, known as the saddled filefish (Paraluteres Prionurus), that is nearly identical to the toby in shape, coloration, and patterning. What doesP. prionurus从这个模仿中获利?出色地,C. Valentini在其组织中有一种致命的毒素,称为四毒素,这种毒素阻碍了捕食,而且看上去有毒也可以像实际是有毒一样有效的捕食者威慑。
这两个物种之间的视觉差异非常微妙 -C. Valentini有单个背脊P. prionurus有两个背刺 - 因此,如果您要购买一个背刺,请确保您得到了自己的想法。也就是说,我应该指出P. prionurusactually makes a very good aquarium candidate in its own right.
喂养
C. Valentinifeeds on benthic invertebrates as well as filamentous and coralline algae in nature, so a varied menu suited to omnivores is required in captivity. Also, hard-shelled foods (e.g., small bivalve mollusks and crustaceans with exoskeletons) must be offered routinely to help this little puffer wear down its constantly growing teeth. Otherwise—and without purposeful trimming on the hobbyist’s part—they may grow to the point that the fish cannot eat properly and will starve to death.
Housing
我看到该物种的最低水箱建议至少20加仑,但我不会建议您要低于30加仑。尽管C. Valentini是一品脱大小的河豚,不需要大量的游泳空间,它是一个凌乱的饲养者和沉重的废物生产商,因此它有助于为所有污染提供更多稀释。
兼容性
在选择坦克伴侣时,请记住C. Valentini可以是鳍nip脚,并且有牙齿易于造成严重损害。绝对应避免具有长鳍或细丝的物种。同种(除了将已知配对保持在较大的系统中的可能性外),并且同型人的选择也很差,因为它们可能引起侵略性。除此之外,C. Valentiniwill tend to get along with most other fish species (discounting any that might harm the toby, of course), but keep an eye out for aggressive behavior in any case. In smaller systems, I would suggest keeping a single specimen by itself.
另外,我会三思而后行,然后再将其包含在礁石系统中。根据保留的无脊椎动物,它可能会解决,但我不会考虑C. Valentini可靠的礁石安全。
