Bahkan pada masa pandemi Covid-19 saat ini, tren merawat ikan hias meningkat seiring anjuran bagi masyarakat untuk lebih banyak tinggal di rumah saja.
Walaupun tidak memakan banyak tempat, terdapat sejumlah tips untuk memelihara ikan hias di akuarium bagi para pemula.
Hal pertama kali yang harus dilakukan adalah memilih ukuran akuarium. Jangan sampai salah memilih ukuran akuarium, alih-alih akan membuat ikan stres dan tidak bertahan lama. Sesuaikan ukuran akuarium dengan ukuran ikan, terutama pada ikan yang dapat tumbuh memanjang seperti ikan arwana.
Berikutnya jenis air dan tingkat keasaman atau pH. Anda dapat memelihara ikan laut dengan membeli air laut. Proses memelihara ikan laut agak lebih rumit karena harus lebih sering mamantau suhu serta menjaga tingkat keasaman airnya.
Perubahan suhu juga dapat merusak kehidupan di dalam akuarium. Untuk itu, jangan letakkan akuarium di dekat jendela yang banyak terkena sinar matahari atau di samping pemanas.
Terakhir, jangan lupa untuk mengganti air dalam akuarium selama 1 bulan sekali. Namun yang harus diperhatikan jangan langsung mengganti air secara langsung, hal ini akan membuat ikan kaget karena harus beradaptasi dengan air baru lagi.
