My ropefish has made me very nervous, its swollen and actively trying to get outta my tank, its dorsal fins are constantly upright, but the most interesting thing of all is the size of its stomach, it looks like it has a few very big lumps, when the light shines on it's stomach, it seems to be see through, now im sure if it was food or poo it would b dark, the thing is though, i haven't fed it in 2 days actually 3 now, worst of all is i dont have a male, i read in a very old book which i happen 2 find at the local fish shop, it says there that internal fertilization takes place, does that mean males or not needed or that the male actually has to penetrate? who knows? i dont know what to do with it, someone said its dorsal fins swell up during spawning, well i can clearly see they have, along with the rest of it.
