I wouldn’t do that. The fish are drinking water with the med in it, and if you then dose the food, that would combine to a possible overdose....also, is the metro and prazi in the GC in the right relative amounts for oral dosing?

@Jay Hemdal , found this: https://humble.fish/internal-issues/ , also while I'm not sure about the relative amounts for dosing in fish collections like public aquaria...it certainly works for hobbyists!
@Humblefish ? My gut instinct is that doing both is overkill and probably an overdose, but I'm not expert.

I prepared some med food the other day, it is not as simple as soaking the food in the drug as you then do not know the actual dose. Here is the basic process: 1) estimate the weight of all fish (I have a process for that). Then, figure that the fish will eat 3% of their body weight/day. Calculate the amount of meds needed to deliver that, and prepare the food (either gelatin binder or dissolve in ethanol and spray onto food). I’ll get the process written up when I get the chance.

Wanted to follow up on this. I rechecked the packaging on some API General Cure, and it says 250 g metronidazole and 75 grams praziquantel per packet, which is half a teaspooon to treat 10 gllons.

I’ll get this written up in a couple of weeks. The big task will be a tool for home aquarists to estimate the weight of their fish. I bought a gram scale and some gelatin. I’m going to cut the gelatin into various fish shapes and weigh them....then, the aquarist just selects from a chart, the shapes closest to their fish. Once they know the mass of their fish, the med food will be easy....

I'm getting the weirdest mental image of you just having a sheet of gelatin on a baking tray with a bunch of fish shaped cookie cutters next to you in order to do this.
How exactly does one know how much gelatin to measure out in order to approximate a fish by the way? I get that people in general are just bags of water, plus a bunch of other stuff, but where does the data come from? I can't really imagine somebody taking a bunch of firefish after they've died and tossing them in a dehydrator to see "oh, the fish is this percent water, and this percent bone, and this percent protein"...although I guess they do it with anchovies?

That's exactly what I did this afternoon! I made a big sheet of gelatin that was neutrally buoyant in seawater (less water than normal). Dead fish are slightly negatively buoyant. I made "fish shapes", weighed them on a gram scale and took a pic of them next to a ruler. Then, I'll post a series of them, and people can use them to estimate the mass of their own fish. Not perfect, but better than not factoring in the fish weight at all. Years ago, I wrote a computer program that would estimate the mass of a fish based on its body style and length. It worked fairly well, but it was written in xBase and that isn't supported by Windows since about 2005 I think.
Sample attached.
