No!!! Don't do it!!! Mixing peaceful Knifefish such as trumpets with the most aggressive... Aba abas will not work out. The aba abas will eventually eat every thing except the gar. Just please for the sake of the fish don't do it!!!!!
The aba aba will likely kill your spotted gar. It may work for awhile but one day you may come home and find chunks missing/eyes missing or dead. Most aba abas end up being a solo fish and needing a large tank. Awesome fish but this is the behavior of aba aba usually. There are a few members that kept them with other big big fish but long term is unlikely. Even then I've seen aba abas take out big arrows, cats, and etc.Thanks for your reply So is it a good Idea to keep Aba Aba & Spotted gar together?
