I have had this little guy in my tank for about 6 weeks without any problems (tanks has been set up for 4 months), togther with an angle, tiger barb, guppies and neons.
About 2 weeks ago I noticed that the dorsal and pectoral fins started to become white and transparent.
There have been no changes in the tank (no new fish, no water change etc) the week prior to this.
I have treated with Piramix (probably same as Melafix in the US) for 10 days and the colour seems to have come back a little and then stabilised but as soon as I stop the treatment the black goes away again.
Last night I noticed that he was coming in the top of the tank more than usual but he still looks lively and energetic.
Could it be fin rot??? and if so how to I treat it and how long will my loach take to recover?
I need some help I don't want to loose him!
