Hello hello. It has been a while because of my obscenely busy schedule lately. Unfortunately, Crusoe has not been getting the attention he deserves and I noticed that for the first time, I have algae on his tank walls and in his gravel! Normally I would just clean it off but I wonder: Would doing a 100% water change harm his cycle? Is a 100% water change for algae even necessary? He lives in a 5 gallon with no plants or mates...aside the algae, of course. It is beginning to get bad, as more has begun growing on the walls and his decorations are turning green, including his substrate.
He doesn't seem to mind but I certainly would not leave it there. I was considering getting those anti-algae tablets I have seen advertised but I do not know if I am supposed to add them before I have algae or while I have it in order to fight it off. I have also considered getting him a tank mate. This, however, can be harder to deal with because I will be traveling in December to my parents' home for about a month and a half to two months and it will be harder to carry two fish rather than one with me.
I am going to fight my urge to do a 100% change if there is an easier way. If I do get him a tankmate, I'd like to get a Julii cory catfish like I had once long ago. However, I know they are social, grouping, fish and I was wondering if any real harm would happen to the little guy if I purchased him alone. Also, I am not sure how to add him to the tank without Crusoe going nuts. I never had a tankmate before and I would like to know the right way of adding fish instead of guessing.
