Hello. Im knew to this site but i have a 35 gallon freshwater tank that i have 2 tigerbarbs in it and a red tailed shark. they have been in there for about a yr and r doing well.I also have a 20 gallon saltwater tank that i am having sum issues with. Im hoping this site can help. Im knew to the saltwater thing so im not entirely sure how worried i should b. lol. it is a reef aquarium. i only have 2 fish in it as of now. one blue damsel and a striped wrasse. i also have about 10 lbs of live rock and sum diff corals. i will most likely ask sum questions in a diff post and c if i cant find sum answers.
