So I went to buy a plant pot on Saturday and the garden center was having a closing down sale.
I ended up ringing my bro in law (Z4s aren't overly good for moving such things) and taking home a 110 litre tank and stand.
I moved all the fish and 'furniture' from my old 30 litre tank as well as the over specced canister filter and used some of the substrate to replant the greenery after being assured by Maidenhead Aquatics that it would be OK as it would be basically a big water change.
At the time we had 3 platys and 7 x 5 week old fry, 5 cloud minnows, a loach and a random Danio that has survived years after his mates died.
They all lived happily together in the old tank. After transferring them we noticed the male Platy had his tail nipped. At the time i just thought it was the fact we kept them in a small container while we transferred everything and filled the tank up.
This morning, however, his tail is even more ragged but I've not seen him being attacked by anything when I'm around, though one of the females may have been gravid and since given birth as she's lost a lot of weight overnight.
We also added 3 peppered Cories yesterday.
Any ideas why he's suddenly under attack or losing parts of his tail?
