Is this a mayfly larva? (And more creepy crawlies from my tank)

[evil Nick]

Sounds like he was a good cleanup and kept the leaches in check. Probably the reason all my MTS got taken out too. I don't know if I have any left

Unfortunately, you really can't. Simply because there's no guarantee that you'd be introducing a native species and we all know about introducing non native species ?.

Can those leaches kill fish? Because my kissing gourami is now dead. Amm 0 rite 0 rate 10

I've got a weird film on the water that won't go away but I think it's just lack of surface agitation. At the moment is a mystery death.

Yep. Did an 80% change Monday night and cleaned my filter tubes trying to get the flow up and it's back again. Didn't see any injuries, but my pleco was eating him so difficult to ascertain.

I believe this is due to a build up of proteins, but I could be wrong. I don't believe your gourami would die from this but i could be wrong again.

I have tried syphoning directly from the surface, only remedy I found is an Eheim Skim350.

My guess your gourami's demise may have been related to the surface film. They are labyrinth breathers thus an oily or viscous surface film would impair breathing, possibly suffocating them.

Leeches generally do not kill fish (unless a fish is infested with them) but they do cause health issues such as anemia and secondary infections. They are hermaphrodites so a single leech can create an entire population. And they are truly a nightmare to fully eradicate.

Wasn't sure if the film would cause the death or not, but I can see where your coming from.

This makes sense, although the film has been there for a while. Could have built up slowly.

I didn't think leaches would kill fish, but I needed to rule it out. I'm switching substrate soon, so they'll go away then when I give the tank a vinegar bath and empty it completely.

Just something to keep in mind. I removed substrate (and all living creatures) from a tank and dumped an entire bottle of ace ammonia in it and let it run thinking it would kill off leeches. Nope. Then completely emptied the tank, brought it outside and dumped in bottles of bleach (filters included). Brought back in and recycled it from scratch. And guess what? Leeches appeared a few weeks later.

Leeches are the equivalent of cockroaches. Their eggs can survive for years and are not affected by heat, cold, drying out, chemicals, etc. They only hatch when conditions are suitable for survival.

Good news is you may have the species of leech that only feeds on plants and not the sanguineous type. Herbivorous leeches are more common in tanks although the opposite holds true in ponds.
