Because sometimes, what you really need for your mermaid OC is that extra bit of uniqueness to it. I tried to aim for as much diversity with this dataset as I could before getting to work, with as many types of real-life fish represented as I could think of at the moment, which is still far from all of them, if I represented all of them in this lora from the start, I'd be here for ages. Still, I went for a diverse selection of types to choose from, and the tags for each specific one is listed below.
Shark: shark mermaid, two-tone skin, grey skin, shark dorsal fin, sharp teeth
Lionfish: lionfish mermaid, venomous spines, lionfish dorsal fin, striped tail, scales
Clownfish: clownfish mermaid, orange tail, striped tail, clownfish head fins, scales
Eel: eel mermaid, very long tail, lamia, eel head fins
Anglerfish: anglerfish mermaid, illicium, esca, sharp teeth, blank eyes, bioluminescence, scales
Jellyfish: jellyfish mermaid, jelly hat, jelly skirt, tendrils, transparent body, transparent hair, biolumiescence, shiny body, tentacles
Koi: koi mermaid, white mermaid tail, red mermaid tail, orange mermaid tail, black mermaid tail, spotted mermaid tail, koi mermaid tail, scales
I definitely recommend you to mix and match tags from these mermaid types too if you wanna have some fun. It will help you get some real randomness to your mermaids, and help them look even more unique. Which brings me to the final set of tags, specifically trained on patterns with little reference, or based on characters with unique tails like Sayu from No Straight Roads or Shirahoshi from One Piece, as well as Ariel's sisters from the Little Mermaid remake. The result here is a little wonky, and often very chaotic, but it does its job decent enough. I recommend playing with the individual tag weights here because the results tend to vary a lot depending on the weight you use these tags at.
Random pattern: random pattern mermaid, multicolored mermaid tail, scales
Finally, weight. I recommend you use this at weight 0.7. You'll find it might be a bit too rigid at 1, but it should work there too, depending on the type. It might change with future releases, I dunno.
And yes, I'm taking requests for specific types of fish to represent in future releases of the model, so feel free to comment if you feel like a specific type of mermaid is missing. As of writing moment, I'm only really considering cethlapods/scyllas and sea snakes for the next release, so any specific suggestions would be very appreciated.
