Transferring 55g fish to 135g. Can I add fish from 40g too? 55g: 3 blood parrot cichlids, 6 giant danios, 5 rasboras, 3 panda cories, and MTS of unknown number. 40g: Paired pear gourami, 2 cory hasbrosus, japanese trapdoor snails, blue and black neons, and glowlight tetras. The BPs will grow almost 10" each so pretend they already are. Another problem I see is the 40g is planted with soil. The 55g is not because BPs dig.
