but my PROBLEM is...my other fish only tank!!! it is constantly at 86 F !
i m scared guys..i dont wanna lose my fish and aneomes in that tank..!! i already have my lights on at night time already...but still it is at 86F!!! and i cant lower my lighting period that much coz i have and plannin on more anemoes..so they require lights....and i have no room or a way to fit another fan like i do with my other tank's heat problem.....
