Tank Size for Jag's
Aloha!
I agree strongly with GER 1023! As a devoted Managuense "keeper... "(Yes, they are a blessed creature not unlike a cat who is an individual!) May I also suggest that it be taken into consideration that You will want to provide a "Sanctuary"for your Jag(s). In choosing, Glass tanks: Rocks and Caves must be provided. If placed in relation to their size and expected growth and territorial nature, can spread out far and take up a considerable amount of space. Often scratching and marring the glass at support points. This can be unsightly. I've tried all kinds of combinations in raising my jag from Juvi to adult.
20 Gallon to 125 Gallon. If you can afford it, Bigger IS Better! to provide the best for these incredible species. I am going to build my own tank eventually, Inside a 20 foot wall and make it a 500 to 800 gallon. There has got to be a way to provide for our "babies" without being ripped off! Good Luck!
