Fighting Fish - Whodunnit?

[Saint Cuthbert]

I have two tanks. A 65 litre and an 85 litre (sorry to the yanks - don't know what that is in gallons!!!)

In my 65 litre fully cycled tank I have 4 sepia tetra, 2 cardinal tetra, 4 ghost shrimp, 2 killifish and 2 platys - and a paradise fish.
In my 85 litre I have 2 dwarf gourami, 3 honey red tailed gourami and 2 honey gouramis and a royal ram.

The paradise fish was in with the gourami but just constantly harassed them (they are all only babies really), till they just hid in the plants....I swopped him with a betta that was in with the tetra's as he had been bitten - but the betta died (most likely from stress or shock).

One of the platys looks a bit chewed as well - the other went a bit rougue a month back but things only happen now when the lights are out. Three cardinals have also bitten the dust in the last few weeks.

Who is the fin nipper?

I am thinking of moving the killifish in with the gourami, and buying more tetra's for the small tank....or should I put something else in with the gourami? I saw a lovely yellow panchax - but can't find any info on them.....or should I just leave things alone.....

I have 3 panchax, 1 male and 2 female, they are lovely fish and especially are they like the upper level of the tank, they prefer floating plants if you want to breed them. I find the best way to get fishy info (apart from you guys of course) is to put the fish name in google and you'll usually find loads of info.

Serpae tetras are well known fin-nippers; I'd keep an eye on them. If the problems have started since the addition of the paradise fish, he could be another candidate: like many labyrinth fish, they are very territorial (which is why it was never going to work in a tank of gouramis).

I realise that now - but when I bought him I was told to just keep him seperate from other paradise fish and bettas.....The gouramis are largely male (as far as I can tell) and they have been getting on fine.

It isn't the paradise fish who is the culprit - he only moved in post any damage.
