Alright, I've officially fallen in love with my 'snail irradication submarine' (aka juvie spotted puffer) - so I'm NOT going to give him to my friend afterall. I have found that if I put him with female bettas - he either goes after them or vice-versa. So mixing him with the 'girls' is not an option. He did seem to mix well with the ghost shrimp - as long as his tummy was full of easier to catch prey like pond snails and/or shrimp pellets.
So I'm eyeballing an empty 29T. I've got a great spot in the classroom to make an 'estuary' model. Basically, it'll be filled with 'grass-type' aquatic plants and slightly brackish. I'd like to mix things like mussels and shrimps with him. What other slightly brackish water fish would go well with this puffer?
