FAQ

Why can copper-containing fish medication not be used in an invertebrate tank?

The toxicity threshold of copper ions for invertebrates is far below that for fish, making copper the most critical fatal toxin for these animals. Misusing copper-containing fish medication or copper-containing algaecide, or using water that has passed through old copper pipework, can cause shrimp, snails and corals to die in large numbers within a short time.

無脊椎動物の水槽で、なぜ銅を含む魚病薬を使ってはいけないのですか。 — 銅イオンの無脊椎動物に対する毒性の閾値は魚に対するそれよりはるかに低く、この種の動物にとって最も重要な致命的毒物だからです。銅を含む魚病薬や殺藻剤を誤って使ったり、古い銅の配管を通った水を使ったりすると、エビ、巻貝、サンゴが短時間に多数突然死することがあります。

What environmental conditions matter most when keeping pet tarantulas and scorpions?

First distinguish the two broad types by native range — tropical rainforest (high humidity) and desert (dry) — because confusing them can be fatal. The substrate must be deep enough for the animal to burrow or moult, the enclosure must combine ventilation with escape-proofing, and a hide and a shallow water dish must be provided; if an arboreal species' enclosure is too shallow and lacks cushioning, a fall can rupture the abdomen.

ペットのクモやサソリを飼ううえで、最も注意すべき環境条件は何ですか。 — まず原産地によって熱帯雨林型（高湿度）と砂漠型（乾燥）の 2 つに分ける必要があり、取り違えると致命的になります。床材は掘ったり脱皮したりできる深さが必要で、飼育ケージは通気と脱走防止を両立させ、隠れ場所と浅い水皿を用意します。樹上性の種のケージが浅すぎて緩衝がないと、落下により腹部が破裂することがあります。

Are a tarantula's urticating hairs an infectious disease?

No, they are a physical defence mechanism. New World tarantulas kick fine hairs from the abdomen with their hind legs, and contact with skin or eyes can cause irritant dermatitis or ocular inflammation, so avoid touching your eyes after handling them.

クモの刺激毛は感染する病気ですか。 — 違います。それは物理的な防御機構です。新世界のオオツチグモは後脚で腹部の細かい毛を蹴り飛ばし、皮膚や目に触れると刺激性の皮膚炎や目の炎症を起こしうるため、扱ったあとは手で目に触れないようにしてください。
