Baliqlar ko'payish ekologiyasi bilan bog'liq bir-biridan qiziq holatlar mavjud. Shulardan biri Janubiy Amerika suv havzalarida keng tarqalgan xarasisimonlar turkumi vakili Copella arnoldi hisoblanadi.
Ular yosh avlodlarini suvdagi dushmanlardan muhofaza qilish maqsadida tuxumlarini suvdan tashqariga - daraxt barglariga qo'yadi. Bunda erkak va urg'ochi baliqlar suvdan sinxron tarzda sakrab suv yuzasidagi daraxt barglariga yopishib olishadi. Urg'ochi baliq tuxum qo'yadi va o'sha zahoti erkak baliq ularni urug'lantiradi. 3-5 soniyadan keyin har ikki baliq suvga tushadi. Keyinchalik erkak baliq tuxumlar qurib qolmasligi uchun ularga dumi bilan suv sepib turadi.
Ikki-uch kunda tuxumlardan mayda ikralar rivojlanadi va ular suvga tushib o'z rivojlanish hayotini davom ettiradi.

How to Buy Bitcoin?
Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage account—you’ll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, you’ll need a digital wallet in which to store it. This might be what’s called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.
