In my experience, birchirs always get ignored. Word to the wise, however since the senegal is a narrow fish, you should buy it first and allow it grow before purchasing the jag. The jag will not hesitate to chomp what can fit in its mouth, particularly if it is not being fed live foods. It will be more likely to fill the void in its diet. Personal jag experience 10 yrs. Just what I've noticed.
Also, my jags grow 1"/month to 3"then 1.5"/month to 8". Growth slows after that to .5"/month
