We have 60L tank with 4 guppies & 2 otos. Have just noticed that one of the guppies tails has a split in it and on examination the other guppies tails are looking a bit "shreddy".
Am wondering if its fin rot and if so what to do.
We normally change water 25% each week but in the last month have only managed to do it twice but when have tested water the nitrites & nitrates are nil. We've had tank since May, fish since August and I've only cleaned the filter once and have never changed the sponges.
We did recently turn the temperature of the water up a bit as our central heating broke and we were worried about the water temp dropping.
The guppies hassle each other a lot but have never seen them bite each other and the otos just hang out on their cucumber so don't think they can be blamed for any tail damage.
What should I do? Am a bit worried about using fin rot treatment in case it mucks up the filter. Should we just step up our water changing for a bit and see if things improve.
