I think that the EBJD would probably get demolished by the Salvini. They can be quite evil. Also(and this is my opinion) you want to add the least aggressive fish first. So if you do try this combo I'd go EBJD, GT, then Salvini. Waiting a week between fish will give the others time to get established. As for a stock list for a 75. i think that the GT, Pink or Marbled Convict, and a Firemouth would be a good setup. Just my opinion.
