I have a 25 gal planned for a young silver, but I`ll buy a 300 gal in about 9 weeks. Can the young arowana live healthy in the 25 gal or should I wait to get the 300 gal one?
a 50 would make a great growing up tank, but i think your 25 would be fine if you change water every 3 days at about 30%. but your larger tank MUST arrive soon coz silvers grow before your eyes man, believe me
