glad to beapart of this thread because I am just recently re-starting my fish keeping. 24 now. had a 55 gallon when i was about 12, so its been a while. i have a new 30 gallon i am getting set up, but for the time a 10 gallon with 4 small redtail sharks and 2 columbain sharks. the tank was set up with the rts for about 4 months and last week i got the two col. sharks and two plants, not sure what the names is, look like tall grass. somehow i got a bad case of ick from the 2 fish or the plants. i am in the process of treating with alittle higher heat and some ick sure from the store. did two 25 percent water changes. found a great article on ick http://www.cichlid-forum.com/articles/ich.php any other help or info on ick and red tail sharks would be great. this is a awsome forum. lots of help here it looks like.
