Has anyone ever heard of hard water causing your crowntails fins to slowly over time get shorter or look melty?
They just start getting shorter and shorter fins but it doesn't look like fin rot, no discoloration, no black or darker colors at all. No jagged edges or raggedy looking fins whatsoever. It's hard to even notice unless I look at old pictures of the fish from a few months back and think hmmm his fins were longer here. No sign of stress to the fish and I always do 100% water changes every 4 days, keep the temp at 80 degrees, etc. This has happened with 2 crowntails and 2 veil tails, but never happens with my plakats or HM's. From what I've read online it happens with crowntails and the veiltails get a "melty" look to their tails. I'm confused as to what it is, or what could be causing it other than this because I can't think of anything different that I could even be doing to make them healthier. I tried medicating when this happened last year but nothing changed. The bettas all look fine and are active, eating, bubble nests, etc. I can't do water changes any more frequently than every 4 days and even after 4 days their ammonia & nitrite level is still at 0. The only thing I can think of is hard water.
Anyone have anything like this?
