I have a question, but first I will tell what works for my Senegals as far as diet and mixing introducing a smaller size Senegals with a somewhat larger one. Like many have said don't do it or watch them. Even that won't ensure that the larger or more aggressive won't dominate food, space, or try to make dinner of the other. What you can do is one or more or all of the following. 1)Feed them twice a day and don't overfeed them. If you are planning to miss a feeding or a day or weekend set up an automatic fish feeder. (For those whose Senegals are conditioned to eat a combo of live, flakes and pellets) 2) A sage friend of mine who has worked in the aquaria business many years suggested obtaining young (small) Senegals, close to the same size, even from the same batch if possible. This way they grow up together. I did exactly as he suggested and he special ordered me two. They have always been docile sweethearts; affectionate to each and leaving other fish alone. And some may say where is the fun in that? I like my mixed tank. Granted as precaution I have no smaller fish in that tank. Also I feed them only high quality different ingredient pellets. Like a different flavor each week. But they also eat flaked food of the other fish which makes easy automatic fishfeeders easy to dispense. (Make sure to experiment once or twice with these feeders for portion control - broken pellets should work too) >>Keep a partial canopy of floating plants. I have floating water wisteria. My Pollies like to wind through it and rest in it, and it brings them out in the daylight for your daytime viewing pleasure. (I feed them once day, once night) The water wisteria also allows light to filter down to my baseline plants. Also it isn't difficult for young Senegals to swim up through it to the surface for air, but in the case of young, small Senegals don't grow it too thick so they can penetrate. I also have caves and hollows. I have my external tank openings covered but on occasion in a hurry have left my old fashioned hinged lid open and they haven't left their premises hunting for greener pastures--er algae ponds. In their native waters and aquariums they are known to take short terrestrial treks in search of better food sources. Hopefully some of the prior information helps new Senegal aka Dinosaur Eels keepers.
Question or ideas please. My angelfish and Senegals grew up together and were and are for their different shapes proportionately about the same size. Suddenly the larger of the two angels has become aggressive once in awhile when a Senegal brushes against it or crosses it's path. Senegals are reputedly not known for having great vision. I know angels can be territorial and aggressive. It has been peaceful toward the Senegals until now and it isn't a knock down drag about fight. The Senegal almost cordially, swims away and the angelfish quickly stops pursuit. I scatter the food through the length of the aquarium, but I know many fish can be possessive, greedy, gobblers. I am thinking the angelfish are wanting to procreate and am (thinking) about moving the angels or perhaps my Senegals to another of my established tanks. I hate to uproot either pair or subdivide the places they like to roam. There is plenty of open swimming space and sight barriers. Rocks, mountains, plants.
Any ideas from any of you wise fishkeeper folk? Sorry about the length of this. I have read to keep the Senegals with peaceful fish of corresponding size. Like I said they always got along. Maybe I should separate to avert a big blowout. Looking at them just now and a Senegal brushed past and touched the big angelfish's tailfin. The angel didn't react AT ALL. Am I over reading this? Thank you in advance.
